I just ordered the comic boards - I order the 7x101/2 and the 81/2 by 11. I like the larger for cuts over 2 yards. I think I will order the 6 3/4 x 10 1/2 for the smaller pieces next time. I have used over 1/2 of the 7 x 10 1/2 pack and will be ordering more.
I really like the way I can store the fabric, either in my bookcase, in drawers, or in containers, I can see the fabric without having to pull everything out in the floor and I can store more in the areas than I could when I just folded the fabric and laid it on the shelve or in a drawer.
