I'm working on my second Family Reunion dress, and despite what feels like great care being taken on my part, I can't seem to get them all even. It seems like there are so many places to mess up? I used a tracing wheel to transfer the markings, then I really tried to stitch an even 1/4" (I don't have a 1/4" foot, I bet that would help), but they still ended up uneven. What do you do?
