When you don't have room, you improvise!! With a 12 ft quilting machine in a 12 by 24 ft building, there is not a lot of extra room for cutting.
Thanks to my DH, we can store and cut batting and two kinds of wide muslin backing more easily.
He mounted a bar on the wall. We feed the fabric behind it and cut what we need, using measurements marked on the wall. This works out really well.
