“Allow yourself to go and do it wrong. Don’t expect to always get it right. It will prevent you from doing anything.”
–Darren Hardy, The Compound Effect.
I realize, as you’re reading the above quote and then comparing it to the title of this blog, they may seem counterintuitive. But not really. What I am sharing with you this week are the steps I take to make sure my quilt blocks are as perfect as possible. However, please realize this knowledge comes from me making lots and lots of mistakes.
Lots.
Tons.
For the most part of the early years of my quilting journey, I was self-taught. From 1986 until 2000, everything I learned about quilting I picked up from library books or casual conversation I overheard at my local Piece Goods or Hancock Fabrics.
I had no idea there were quilt magazines.
I had never heard of Quilt Guilds.
And my local community college offered plenty of classes in crocheting, knitting, and garment construction, but none in quilting.
I checked out every book my local library had on quilting and read them thoroughly. This was the early eighties, so templates and scissors were used. Fabric decisions were divided into yardage of lights, mediums, and darks. There was no internet to Google search anything. Honestly, I learned a lot, but a lot of what I learned was from my mistakes. With this blog, I hope to help you avoid some of the blunders I went through as I tried to make my quilt blocks as perfect as possible. The following are seven steps I go through with each and every pieced quilt block I make in order to get them as close as possible to perfect (I handle applique blocks a little differently).
- Starch The Fabric Before Cutting
Whether you prewash or don’t prewash, starch your fabric. Starch will stabilize the grains of the fabric. This will help you cut accurately no matter if you’re cutting across the width of fabric, the length of the fabric, or (especially) if you must cut on the bias. The bias can be really stretchy and easy to distort. Starch keeps the fibers in place. Starched fabric is also easier to control, and gives you better accuracy when cutting. Seams stay pressed in the direction desired – either to the side or open. And (bonus if you quilt your own quilts) starch makes the quilting process easier.
So how much starch should you use? More than what is used when you iron clothes. You want enough starch in the fabric that the fabric stops feeling like fabric and more like a piece of paper. The starch should be pressed into the wrong side of the fabric and may take several applications. Don’t saturate the fabric with starch and then try to press it until it’s dry. This may distort the bias, and it leaves flakes of starch everywhere. Spray several light applications of starch and press those into the fabric one at a time until the fabric feels like paper.
When I mention this in a class I teach, the next complaint questions asked concern time (That takes too long! I just want to quilt!) and doubts about how much the starch really helps. Well, it’s kind of like this: Which kind of paper is sturdier, tissue paper or construction paper? The obvious answer is construction paper. Fabric is sort of like this. Unstarched fabric – even if it hasn’t been prewashed to remove the finishes – is like tissue paper. It can wiggle and move out of place under your rotary cutter. A starched fabric is sturdier and stabilized. It won’t move as you use your rotary cutter, and the bias or other cut edge won’t stretch out of shape.
As far as starch goes, there are a variety of starches and starch substitutes on the market. Some of them cost more than others and some work better than others. When I use starch, or mention starch in my blogs, this is the kind I mean:
Spray starch. There are other kinds of starches out there – other sprays, kinds you can mix yourself, and even liquid starches you can dip your fabric in. The kind you use is a personal choice, just be sure to read the label. Starch is made from grain, such as wheat, rice, or corn. I’ve always heard because starch is created from a grain, they can attract silverfish and other critters, but personally, I’ve never had this happen. This kind of starch – the “real deal” starch – holds a crease better than anything else.
One last word about starches. Spray starch is readily found in grocery stores and drug stores. It is also found in dollar store establishments. Allow me to offer a word of warning: Not all spray starch is created equal. The kind at dollar stores usually has a higher water content than the kinds at grocery and drug stores and may not work as well.
Don’t get spray starch confused with sizing. Both come in aerosol spray cans and are usually found sitting side by side on the grocery store shelf. Sizing is different from starch. Sizing is plastic based, so it works great with synthetic fabrics. However, it doesn’t give fabric the same stiffness that starch does. Sizing is more like the finish that’s sprayed on quilting fabric before it’s put on the bolt.
There are also starch substitutes available, such as Best Press and Flatter. These are more like sizing than anything and they’re a bit on the pricey side. A bottle of Best Press is currently $12.87 on Amazon and Flatter is $14.41 (also on Amazon). A can of Niagra Spray Starch at my local grocery store is $3.59. Best Press does have something called Best Press 2, which does leave your fabric truly feeling like a sheet of paper, but it is also expensive, clocking in currently at $12.87.
Terial Magic is another choice for making your fabric stiff. This liquid can be found in a regular bottle or spray bottle. With either, you saturate your fabric and let it hang to dry until the fabric is damp. Then press it completely dry with a hot iron. This product does leave your fabric really stiff, but the process takes longer than treating your fabric with spray starch. However, it is messy and currently costs $15.49 for a 16 oz spray bottle. I do think this is a handy-dandy notion to have on hand for non-quilty crafts.
While regular spray starch is my obvious preference, I do realize it can leave your pressing surface a mess. I have found covering my ironing board or pressing surface with freezer paper is a great way to avoid those brown stains. Cover the area with the freezer paper, use a hot, dry iron to press it in place, and you’re good to go. When it needs changing, simply pull the freezer paper off and repeat the process.
- That ¼-Inch Seam is Pretty Important
This – keeping a consistent ¼-inch seam allowance – was one of the hardest skills for me to master. I came from a garment construction background and the seam allowances are a bit bigger for most of those patterns. That ¼-inch seam just looked so tiny compared to what I was used to.
However, let me add this: The ¼-inch seam is NOT the Holy Grail of Quilting.
It’s not. The finished size of your quilt block is as close to the Holy Grail of Quilting as you will come.
While it is true that most quilt patterns, or quilt drafting programs such as EQ8, use ¼-inch seam allowances and learning to sew a consistent one is pretty important, quite a few other elements work their way into the correct finished size of a quilt block.
This is why it’s so important to make a test block preferably out of the same fabric you’re using for the rest of the quilt and using the same thread. Make the block, pressing it as directed in the pattern as you go, and then measure it. If the final product matches the finished size given in the directions, plus ½-inch for seam allowances (for instance, if the finished block should be 8-inches and your test block measures 8 ½-inches, the extra ½-inch is your seam allowance for joining the blocks together), you’re golden. Cut out the rest of the blocks and get busy.
However…there are some factors that may contribute to the block being just slightly less than the required measurements. Sometimes it’s the thread. Personally, I like a two-ply, fifty-weight thread such as Aurifil. It’s a thin, yet strong thread, that doesn’t take up a lot of room in the seam allowance. If you’re block is coming up just a bit smaller than needed, you may want to switch up your thread. Another factor which may shrink up your block a bit is your pressing. Sometimes we don’t press blocks completely flat, but have a bit of a tuck, like this:
Those tucks keep the block from being completely flat and the block will be a bit smaller than needed.
Finally, we may not have a perfect ¼-inch seam indicator on our sewing machines. If you have a machine which is specifically made for quilters, chances are your quarter-inch foot or mark on the throat plate is pretty accurate. But you need to be sure. You can measure over from the edge of the fabric to the to the needle tip with a measuring tape. If that’s a quarter-inch, things are fine. However, you may see you need to move the needle over a little to the left or right.
There is also this tool:
The Perkins Perfect Piecing Seam Guide. Generally found for around $7.00, the guide is placed under the presser foot. There is a tiny hole exactly ¼-inch away from the edge of the guide. When your sewing machine needle is positioned to cleanly go through this hole, you’ve achieved the perfect ¼-inch seam allowance. Again, you may have to move your needle over either to the left or right to get it to insert in the hole, but you’ll have the assurance of knowing you are at the exact ¼-inch spot on your throat plate.
There is also a test you can do yourself without the Perkins Perfect Piecing Seam Guild. Cut three strips of fabric, one dark and two light, 2 ½-inches wide by 6 ½-inches long. Sew them together along the long side of the strips, with the dark strip in the middle. Press the seams towards the dark and then measure your block. If the block measures exactly 6 ½-inches square, your ¼-inch seam allowance is dead on.
There are also quarter-inch presser feet available for most machine models. Overall, these are really great, but it’s a good idea to do the fabric strip test mentioned above to be sure. Sewing machines made primarily for quilters (e.g. “Quilter’s Editions”) usually have the quarter-inch foot thrown in as part of the package. If your machine doesn’t have one, a generic one can be purchased, just be sure to know if your sewing machine is a high or low shank.
Two last tips: First, some quilters simply opt for sewing everything at a scant ¼-inch seam allowance. This seam allowance is simply a thread or two less than a full quarter inch. This scant quarter inch will allow for any thick thread or tucks made when pressing.
There are scant quarter inch presser feet, too. Second, if you’ve constructed a quilt block and it measures just shy of the required size, go back and re-press the block with the seams open. This will free up a bit of the fabric taken up by pressing seams to one side and may make up the difference, so your block is the perfect size.
Again, let me emphasize while the ¼-inch seam is important, it’s not the Holy Grail of Quilting. The finished size of the block is. As you make a test block, it could become evident that you need to take a significantly smaller seam allowance or a larger one in order for the block to come out the size needed.
- Strip Piece as Much as Possible
I wrote an entire blog on strip piecing – it’s history, how to do it, and how it’s so effective: https://sherriquiltsalot.com/2024/11/20/when-and-when-not-to-strip/. Strip piecing saves time and fabric and is more accurate than cutting each individual piece of the block unit. While you can’t strip piece everything, there are times you can. It pays to know when this technique can be used and use it as often as possible.
- Pin or Glue Baste Your Seams
When I first began quilting, I came from a garment construction background. Between setting in sleeves and collars, making buttonholes or putting in zippers, nothing was done quickly, and you secured everything with pins before you began sewing. Some of the quilters who befriended me early in my quilt journey, didn’t use pins at all. They simply held the fabric with their fingers and sewed – fast! I assumed, by watching them, that pins weren’t necessarily needed in quilting. However, as I had some struggles with the seams, I soon figured out that pins were still my friends, and I needed to use pins with my quilting.
Of course, pins are used to hold two solid pieces of fabric together, such as seams. Some quilters pin parallel to the edge of the fabric and some pin perpendicular to it. This is kind of a personal choice and what works best for you. If I am pinning large pieces of fabric together (such as borders to the quilt center), I tend to pin parallel to the edges of the fabric. I find this method holds things together better and supports the weight of the material.
However, quilts have lots of seams and sometimes those seams must join together nicely. There are a couple of ways I go about this. First, if the pieces I need to sew together have nested seams, I place a pin so it intersects both seams and they stay nested.
If the seams do not nest, there is a technique you can use or a special pin to employ. For the technique, be sure to match the seams, right sides of fabric together, and place a pin in the seam at an angle. Don’t try to insert the pin in the fabric, just leave it standing at an angle. Then insert two pins perpendicular to the fabric on either side of the seam. This pinning technique tends to hold the seams in place well.
If you don’t want to use this technique, you may want to purchase fork pins:
Fork pins aren’t expensive and work well to keep fabric from shifting out of place. Simply match your seams and pin perpendicular to the edge of the fabric, on either side of the seam. The seams won’t shift and will match up nicely when you sew the block units together. Fork pins also hold fabric weight well. I have used them to sew heavy borders to a large quilt.
When sewing a pieced block or block unit to a solid piece of fabric (such as a quilt block to sashing), be sure to have the pieced block on top of the solid piece of fabric and pin it in place either parallel to the to the edge of the fabric or perpendicular, depending on which way works best for you (unless matching seams is part of this equation). The reason you want the pieced unit on top is the presser foot is pushing the top fabric into the bottom one and it’s easier to keep things lined up.
Pinning (and the use of a leader and ender) helps keep your fabric edges lined up when you begin sewing. If you don’t have those pinned into place, as the feed dogs engage to move your fabric over the throat plate, they will grab the bottom layer first and then engage the top layer. This will cause your fabric pieces to look like this:
Sidenote: Also check your sewing machine’s manual to see if your machine has dual feed – this means it has two separate sets of feed dogs. One set is beneath the fabric and the other is on top. If your machine does have dual feed, this also helps to feed the fabric through evenly.
Earlier, I mentioned pinning or glue basting. There are certain types of quilting fabric I would much rather glue baste than pin. The first is wovens or homespun. Neither of these fabric types are tightly woven, so the larger holes allow the pins to slip out pretty easily. A quick swipe of a glue stick and then a moment of drying allows the fabric to hold together. I also glue baste quilting flannels. The slickness of the fabric (due to a rayon/synthetic blend) means pins can slide out of place or the fabric can stretch, but glue basing keeps everything which needs to be held together, held together, until the seam is sewn.
- Learn to Appreciate Your Seam Ripper
We all make mistakes. Sometimes the only person who is bothered by a mistake is us. Other times, the error may throw off quilt construction, and then a seam ripper will come into play. It can undo any sewing mistakes, and you can begin again. No one will know but you. Don’t be afraid to use the ripper.
Remember, the blade on a seam ripper does dull overtime. Be sure to replace your seam ripper as needed.
- Square Up as You Go
Sometimes a quilt pattern will give you each block unit’s measurements as you make them. For instance, a pattern may tell you to make 18 four-patch blocks, and they should measure 4 ½-inches. This is great information to have. You construct your four-patch blocks, and then you can take them to your cutting mat and measure them, trimming if necessary to get the exact, needed measurement.
Other patterns may not include each block unit’s measurements. This is another reason test blocks are important. You can measure each unit as you construct it and make notes on the pattern’s directions. Typically I tend to make the first unit or two, and measure see how close I am to the needed measurements. Then I can trim it down to size. If something has gone terribly wrong, I’ve only messed up a couple of units, instead of 20 or 30. As long as the initial units are good, I can construct a dozen or more and then trim.
Squaring up like this – each block unit, then each row in the block, then the block itself– really gets your quilt block as close to perfection as you can. There are too many factors in play if you wait until the very end of the construction process.
- Press Carefully
Before we go any further with this point, let me remind you that pressing is an up and down motion, not a back and forth one. As you press your quilt block or unit, you literally lift the iron up and down so the block and its seams aren’t stretched out of shape.
As you press, be sure to press to the dark side, so there will be no shadowing and the seams will nest. If your quilt pattern gives pressing directions, be sure to follow them. Press the block flat, so there are no tucks. And if your block is just a bit too small, try pressing the seams open. This pressing technique can free up as much as 1/8th of an inch of fabric per seam.
Finally, there is that age-old argument of steam or no steam as you press. Personally, I like steam, but I would rather lightly spray my block with water and then iron it than keep water in my iron. I think misting and then pressing works better – at least for me. Again, this is a person decision. The main objective is to press the block flat
It’s so wonderful to be a quilter now. There are so many references and sources to search if you have a question or want to learn a new technique – unlike when I was struggling to learn in the early eighties. What hasn’t changed too much are the basics – from starch to pinning to pressing. To make a quilt block as perfect as possible, it’s the attention to the basics that makes the difference.
Until Next Week,
