I fold all my fabric for backings onto half bolts. Every time I go to a fabric store I ask if you have any empty bolts, that I can have for free. Almost all stores will give them to you. When I get them home I cut them up with a box cutter. you can get 4 half bolt boards from one bolt. one side is already in half, so I cut off the ends where the writing is and then cut the one solid side in half. Then take your fabric and fold in half and wrap around. If I have a nice large piece I have been measuring it first, and then adding that slip of paper on the end of the bolt. That way I can tell in an instant if I have enough for the backing of my current quilt. These mini bolts will stand in a bookcase like books are lay down on the shelves. Works for me.
