since I am putting the zipper in the middle of the back should it be smaller then the pillow or the same size?
I always cut 1 inch allowance. The pillow form is puffy, not flat, so it takes more room than just the standard seam allowance of 5/8" in regular sewing. The two pieces for the back will be 17x 9. That should cover where you turn under for the zipper and the 1" allowance. Just to be sure, make the back with the zipper inserted and then measure it to be the same as your front piece.
ok so the front will be cut into a 17x17 square if my backs are equal. then I stitch with a 1inch seam allowance to attach the zipper. Thanks Jerrilyn I think I have it now
Hi Lor...I am not sure Jerrilyn was saying you needed to sew a 1" seam allowance..I think she was saying that you will need two pieces of fabric for the back of the pillow...each one will need to be 17 x 9...the zipper will go in the middle, across the 17" width...perhaps I have misunderstood what you were saying above...
