Tip of the Week: Accuracy
Here are a few tips that will help you achieve greater accuracy and finished blocks that come out to the size you intend.
1. Don't rush the cutting process. Slow down to make sure that each piece of fabric is cut correctly. Use the same brand of ruler throughout a project. We like Creative Grids for both their markings and non-slip backings. Using the same line of rulers throughout might not always be possible, such as when your project calls for a special ruler, but when you can stick to your favorite brand.
2. Make a consistent 1/4" seam. Check your 1/4" presser foot to determine if it's making an exact 1/4" based on where you place your fabric. Sew a seam and actually measure it. Too often what looks to the eye to be 1/4" is actually quite scant or overly generous. You can also slide a ruler under your presser foot and gently lower your needle to see where your 1/4" is. Note that some patterns specifically call for using a scant 1/4" seam and some quilters consistently sew using a scant 1/4" seam. Experiment and see what works best for you.
3. Pin, pin, pin. Pin every intersection when piecing and remove pins as you sew up to them after your machine needle has pierced through the multiple layers of fabric that are at the seam intersection. Stop sewing with the needle in the down position, gently remove the pin (don't sew over them!), and then proceed with your seam. See image above.
4. Press like a pro. Always "set" your seams by applying heat to the stitch line before opening it up your fabric to press in one direction or to press a seam open. Press gently so that you don't stretch your fabric, but make sure that there is no "play" left once a seam is pressed. In other words, make sure your seams lay nice and flat as you piece your blocks together. We love the starch alternative Best Press and sell it here at the shop in 16-ounce spray bottles and by the gallon for refills. It's an amazing product.
5. Measure as you work. In addition to measuring and squaring up quilt blocks before doing your final assembly, be sure to measure block elements as you go.
6. Use the right tools. In addition to rulers, there other tools that can help with accuracy. Use a rotary cutter that feels good in your hand and replace the blade when you notice "skipping" or just have trouble cutting through layers of fabric. Use a good quality cutting mat, but unless you're cutting a piece of fabric larger than any ruler you own, don't rely on the mat for measuring. Your rulers are more accurate. A 1/4" foot (see above) is essential for even semi-serious quilters, and consider investing in a single hole stitch plate for your machine if you don't already have one. Make sure your work area has good lighting.
