I am lucky in that I have a 25x13 foot room. But it also has a daybed in it and is lined floor to ceiling with book shelves. (I always wanted a library and when we bought this house I claimed that room for that. (this was before I started quilting. So now I have a corner for my quilting, but I still have a large enough floor space to sandwich a king quilt. My only problem is that it hardly gets any natural light.
