I started cutting and preparing my fabric and ended up with only 18 pieces. One piece is 11x17 1/2 instead of 11x18. I hope that isn't a problem. I don't think that half inch will make a difference. If there will be 20 in the 3 month group, I will have to send a different piece of fabric. Can I possibly send one 11x18 piece of plain bright fabric and several 11x4 pieces of the stripe fabric to go with it? Is that asking too much or should I just stick with a different piece? Sorry about all the questions.
