I have been reading everyone's posts on design walls for the past year and never really took it seriously that you could put the felt up and then the blocks would magically stick. Well, I was recently given many yards of 72 inch wide felt (some I used as batting and the quilt washed just fine). I decided to pin some on a blank wall I have with just push pins and GUESS WHAT????? My blocks stuck to the felt and have been in place since Monday! I am a believer now. Thanks to all who posted on design walls!
