When I drew it all out on paper it appears I have almost .75" between the twister squares using a 4" square so I think I'll be okay. But I can also see the advantage of cutting w/scissors vs the rotary cutter! I did get all the silly squares trimmed to 4" yesterday. Today I plan on being able to lay out the grid and then start sewing the initial rows together.
I had no clue when I purchased this pattern/kit that the process was so tedious! Holy smokes! Not sure that I'm likely to do another quilt of this type.
