I have assembled many group quilts and everyone has their own idea of size (no matter what is specified). The very first one I did was a Christmas quilt made with 4 patches and each quilter made 6 blocks of a certain size. Well...so much for each one being the same.LOL But I trimmed and assembled and everone loved the quilt. It was far from perfect but made with LOVE and that's what counts.
