I just received my AccuQuilt Go dies for the double wedding ring. How much fabric do I need if I make all of the center pieces the same color? I want to make it in batiks and have quite a collection but want the center pieces all the same but have no clue as to how much I will need. Oh yes, this will be a queen sized quilt with 10" tuck and 12" extra on each side .
How do I calculate this amount? Thanks much. Sue
