Remember to add at least 1/4 of an inch for the seam allowance.
When working with square or rectangular cushions, avoid bulk in the corners by trimming the seam allowance and turning the fabric using a knitting needle to poke out the corners.
If making your pattern from scratch, don't forget to allow for at least a one-half inch seam allowance on all sides.
Don't forget to add a seam allowance if your pattern doesn't already have one built-in.
Sew pattern pieces front sides facing with a one-half inch seam allowance all around using a stitch length of 12 to 15 stitches per inch.
