I've just finished piecing the quilt top for the DQS 11. I pressed it and I've just measured it - it measures 18 1/2" square. Oh No! The maximum size allowed is 18" What should I do? I can't trim it, or I'll lose the points. Should I keep going and hope that it shrinks 1/2" if I wash it? Or should I start again? Advice please?!
