FYI --I've been making tons of potholders this fall, both for craft shows and Christmas gifts. I wish i had stock in insulbrite. I've used so much.
For what it's worth. hobby Lobby's is only about 18" wide. The last I purchased at Joannes (5yds with coupons) is about 40 inches wide. Cann't remember what LQs was priced or how wide.
