I only buy Moda pre cuts. I have a Go so cutting my own is no problem using my yardage. Each one is cut the same size. I had problems with the 6" square die but was told to use a thin piece of paper on the die before the fabric and that solved the problem and I was cutting a lot of them not on grain which caused stretching of the fabric when cutting. I found most of my problems are user error in quilting.
