The blocks are just amazing, ladies! Wonderful eye candy for today.
My gut feeling about giving Joan's family a quilt is this: Joan said more than once that she had So. Many. Quilts. She was running out of room to store them. That being the case, I'm sure her family had all they wanted of quilts that Joan made herself. I agree they should be asked, but think they will probably tell us to donate a quilt.
I've been going through old posts and old Booms, looking at the many beautiful blocks Joan made for us all. Reading her posts, she sounds full of life and plans to be with us forever. How quickly things can change! Hug your loved ones all you can!
