I saw on Simply Quilts with Alex one time that if the block is too small just make a small border around it to bring it to the proper size. I tried this and its looks fine. I have passed this on to my quilters. If the block is too big I have taken it apart and sewed it so it came out the proper size. In a group quilt we all made blocks for I am sure the lady who made it would be looking for her block. Never would I of hurt her feelings by leaveing out her block. I hope these tips may help your delimina. Helen
