Rikk, my guess on your fabric is that there was some stretch in it that you didn't notice. It isn't actually hard to miss in some of the wallyworld fabrics. I bought some really nice olive fabric awhile back that felt really nice in the store, but when I got it washed and was getting ready to cut it, I found out it had a stretch in one direction. I cussed so loud the cats wouldn't come near me for days.
