I am blessed. My space is the upstairs game room. No kids, so I get the whole room to myself. I called it the Eagles' Nest, my husband, Keith, calls it the Crow's Nest. It doesn't matter what it's called, Keith has bad knees and very seldom comes upstairs.
We bought this house specifically so I would have a place for my long arm. The best thing about having a hidden space is that I don't ever have to put a project away until I am finished with it.
