It's kinda good to hear that so many of you have your LR or dining room as your sewing room! I'm like a lot of you that I like to spend time in the evenings with my hubby. I sometimes cut on the dining room table. Now I won't feel bad if I do all my cutting there!
My sewing room is half of our upstairs spare room. My half is probably 15x20. We don't have a basement, so the other half of that room is storage. But the house has a hip/gambrel roof, so the walls are angled. Can't hang anything up and any shelving has to be short.
Eventually, I'll move into our bedroom. We're in the progress of putting a bedroom on downstairs. We plan to die in this house LOL and want everything on 1 level. But since we're doing it ourselves, it will be awhile yet! LOL
