It works beautifully. When you're done the quilt is very stable and doesn't shift at all. I used size 12 perle cotton that comes on the balls but next time I'm going to use size 20 crochet thread. I found doll making needles at JoAnn's that are easy to thread with thread that size and they're nice and long and very sharp.
I have two sizes of boards. I have a 6 foot set for smaller quilts and a 10 foot set for anything that won't fit on the 6 foot boards. I store the boards on the floor behind my couch in the family room. I have two folding tables from Wal-Mart that I put together end to end when I use the 10 foot boards. Sharon doesn't show it in her videos but it helps to tape the top edge of your quilt to the board with painter's tape.
