I didn't read all the responses before starting my "say". THIS is/has been one of the most difficult things for me in learning to quilt. I am very obsessive . . . try to do things "just right" and was told early on about the pressing of seams. I've handpieced several quilt tops as well as sewn a few and work very hard to get the seams "just right". I know about "nesting" etc. But speaking for myself . . . with the very BEST I can do, I come to places where it just doesn't work. It is QUITE frustrating, and I must admit that sometimes I felt like just quitting. I finally just "pinned down" some excellent quilters that said "it doesn't always work out and sometimes you just have to repress a seam differently or work on it to get it to lay as flat and nicely as possible". This did not free me to start being haphazard at all, but I am more accepting of the places I sometimes come to that "just don't work out"! When I have time I am going back and reading every word you fine ladies contributed here. I felt pretty certain it will make me feel even more comfortable.
