I got this back from the quilter today. The fabric is something that Mom bought many years ago, thinking she would make a simple quilt to match one a friend gave her. When they moved to a retirement facility (in 2004, I think) all the materials were neatly folded and waiting. I took them - along with a good portion of her unused stash - and finally decided what to do with it all. It's "whole cloth", meaning no patchwork, but I did seam together two pieces to make it large enough for her bed.
Now it needs binding and finishing. This is without question the biggest piece I have ever worked on. If I'm not heard from in a week, send a rescue party!
