Oksewglad, I love that rectangle idea. I have a lot of collections of fabrics from back when I was swapping mostly in 10" squares, one of them I gave up on ideas and sent out in one of my boxes was a collection of angel fabrics. It would be just like stained glass and a marvelous way to use up a theme in subject matter but not style or color.
I'm going to send the lady a link to this image!
In my own sewing stories of the Purple Quilt, I just finished pressing the quarter border units which are now done. Next stage is the squares, they are all pinned. Goal is to sew all of them today, or at least about half and also press them, but I'm feeling a bit lazy.
