I never have seen insulbrite at our walmart. I always have to wait until I take a 60 mile trip to Joanns. I can order it though.
Our joanns which is 35 miles from me is moving south, so it will be about 45 miles away. I feel I can't win for loosing!!
I use insulbrite and a piece of warm and natural.
I love my potholders!!
