I was using templates that were off by 1/8 of an inch. At that time, I thought that a purchased template "had to be right" - not so! So I was wondering why I almost always had to ease in a certain piece of the block! It never even occurred to me then that the pattern was off. By the way - crossgrain usually stretches more than lengthwise grain.
