I hold to the theory that it is MY quilt... and as long as I am consistent it will be fine! When I am working on a block swap, then I do a lot of the things already suggested and try to be as close to perfect as humanly possible. When I first started quilting I saw a lot of Mary Ellen Hopkins on TV, and I loved her saying that it is YOUR 1/4 " and as long as you are consistent, it will all work out fine...
