For accurate patchwork the 1/4″seam allowance is essential. Watch this video to find out how to sew an accurate 1/4″ seam.
Description
You need three pieces of fabric, each cut 1 ½” wide x approx 6” long. You then need to sew them together with your seam allowance; press, and then measure the middle strip by placing the ruler on the right side of the fabric: it should measure 1”. If it is less then your seam allowance is too big and if it is more then your seam allowance is small. Adjust until you get it right and mark the bed of your sewing machine, in front of your sewing foot, so that you can use this as a guide in the future.
How to achieve an accurate seam allowance with the help of your machine. Once you have mastered this, patchwork is so much more enjoyable with much less reverse-sewing!(unpicking!)
