How do your blocks come out? What is their size compared to what they should be?
Here's how to figure out how to sew a perfect 1/4" seam. Contrary to popular belief, all presser feet are not 1/4". And even some the 1/4" feet allow the fabric to push up against the bar and then the seam is too wide.
Cut 3 strips of fabric that are 3 1/2" long and 1 1/2" wide. Sew one strip to another along the long edge. Now sew the third strip to the other two along the long edge. You have 3 strips side by side. Press the seams carefully to one side. Measure the width of the block --it should be 3 1/2" wide. ( It should be a
3 1/2" square.).
If it is wider that 3 1/2", then your seams are too narrow. If it is smaller than 3 1/2", then your seams are too wide.
Accuracy counts in quilting because the blocks and sashings need to match each other. It's probably the only kind of sewing where 1/4" is a large discrepancy.
Measure the amount of space between where your needle meets the hold in the faceplate and where 1/4" inch should be. Put a piece of blue masking tape or several small post it notes at that mark. This will help you "see" the 1/4".
Sonflower has a "piecing basics" class this summer to help you sew these 1/4" seams as well as about 4 other kinds of shapes. We want you to be successful. Check out our newsletter for times.
