After I had been quilting for about 6 months a friend asked me to attend a small local quilt show with her. I was told that this was put on by women who had been quilting for over 30 yrs and all were considered to be experts. Well, it didn't take me long to discover that their workmanship was no better than mine. That was a tremendous help to me because I then learned to relax, which in turn improved my workmanship even more. I too think it is rude to turn in a block for a block exchange that is not even pressed. We all have off moments, but there is a difference between doing sloppy work and just having a hard time assembling a certain block.
