I was so happy to come across (via Pinterest, of course!) the directions to knit one of these rag rugs. (Amanda Jean Nyberg, author of the Crazy Mom Quilts blog, happens to also be the co-author of Sunday Morning Quilts, the book that helped to shape my new approach to quilting last summer.)
The directions call for strips of fabric 1/2 -1" wide (or somewhere close to that) - the very thing I've been saving for years because I couldn't bear to part with them. So, I have a nice supply already started and look forward to making one of these rugs when I've accumulated enough strips!
