I had to sample this twister myself today, placed tape on my 4 1/2" square ruler as directed in an earlier tut., cut four 6" squares in purples and blues, and a 4" wide border all around. Put a new blade in my rotery cutter, and cut as directed. I was really happy with the results, will probably do the larger pinwheel to make a quilt for my grandson, should go pretty fast?! :wink:
