I'm not sure the OP was asking if there are any celebrities HERE on the board. I think she was just asking if there are any that are known to quilt at all.
Knitting seemed to be the rage for a while a couple of years ago, it seemed like everyone in Hollywood was having knitting parties. The only celeb I can think of that quilts is Marie Osmond, and that's only because she was featured in magazine ads for a while.
