My quilting frame is in the basement, with a rolling chair and bookshelves behind it for my stash. The rest of the room is taken up with a treadmill, punching bag, drumset and DS's little man cave.
My real sewing room is my diningroom, which is open concept with the living room, so, if I didn't have any furniture it would be 12'x16', but with furniture, my "area" is the diningroom table, with a rolling cabinet beside me that has a small ironing surface on it, and a few cube organizers against the wall - hidden from the front door by the computer armoire.
But, now that we don't need the "armoire" anymore in this age of laptops, I've commandeered it for stash too! LOL
And no, I won't show pictures, because even my mother won't visit because of the mess!
