I have always found that if I'm having a problem with a quilt that I have never made before, it helps to put it away, work on something that is a little easier, and do some research and learning... not just about the quilt that I was having problems with, but quilting in general. Usually, something will "click" and I will figure out what I need to do and can go back to that problem quilt. Or if that doesn't happen, I will change what I was doing.. cut it up for different blocks, use it for a scrap quilt or something else.. rather than just let it sit there unfinished for years on end.
