amazon.com-I am waiting for the 9th packet of comic boards. At 9.50 for 100 and acid free they are a bargain. Easy to cut as well.
I am reorganizing my room as we speak as DH hated the plastic container on the floor. 4 shelf units and a dresser. I will admit it looks better and is more organized that it was and I can see what I have now. Only problem is Ican also see the tops I have made and not quilted. Love to design and make the tops-hate to quilt them!!
