math challenged quilt with log cabin blocks
My DIL asked me to help her make a quilt, diagram included here. The only real measurement I have is it has to be about 80" square. If the inner on-point square is about 60" corner to corner, I think - with my limited knowledge of math - the sides should be about 42", and here is my problem. 10 log cabin blocks are to go along each side of this square, and if I change the sides to 40" the log cabins will only be 4" finished. They are meant to be 7 strips accross, so the strips would have to be 1/2" wide. Does this size seem feasible? I think it would be a pain in the butt. Anyone done anything like this, and hope some brainy person can tell me it my figures are correct, thanks for any help.
