I think something like that happened with some sort of swap Shadow Dancer did, and her chair ended up remaking everything. :shock: You could check with her, but I think she said it wasn't part of this board.
Here are some photos of different ones that I cam across

For instance a full size would start at 88" long by 14.5" 6 people make rows and you end up with a 88"X87" quilt.
Small quilts would work a bit different. Let's say we're wanting 36" wallhanging. The first makes a quilt of 36" X 6" and 6 members add to make much less work. :)
