Just to add, I have Deb Tucker's ruler & it is a BIG help. When I had problems I just went to her video & it was a huge help also. It is a little more money but well worth it IMHO. I am 1/2 way thru my quilt & really have had no major problems to speak of. Try Deb's video & I am sure that will be a big help.
