I made this one (which was supposed to be a Christmas present for my Mom) all out of vintage sheets. Even the back is a vintage sheet:
It's rather large - 60" x 90". I'm thinking when I get it washed and dried, I really need to try it on Jessie's bed - with an extra row to the width, it might make a great spring/summer quilt for a little girl's bed. And I have enough of these squares cut out to do at least 2 more quilts - an old sheet goes a long way.
