Thanks Moonpi and Klue!
It's not so much as a shifting problem, as just sewing them together. I can't just line them up them edge to edge, as if they were regular straight cuts. To do that leaves them almost 1/4" off on the edges. This is the first time I've sewn diagonal cuts, and hopefully my last! lol!!!
Moonpi, I really like your idea! But my mind can't do degrees, etc! lol!!! Plus, I've already got all the pieces cut. {If} I ever do this again, I might look for some ruler that does the degrees for you, and try your way! It does sound much easier!
Thanks so much!! :)
