First, the front and back were cut at 8 1/2" but after quilting, they measured 8 1/4". (Not a big problem) When sewing the zipper to the pieces with soft and stable it would not lay flat - too much bulk. Followed a pattern on You Tube. Next time I will remember to use a seam allowance of 1/2"all around. Also, had trouble turning the pouch inside out.
