I have a Studio.....
when we moved into the house, I used the formal dining room
after a few months of the kids NOT using the Rumpus room, I "confiscated" it
When we had a home-business, the room got doors
now it holds the majority of quilty stuff, and is my Studio.
don't think it is pretentious, just a case of name-it-and-claim-it
....kids know what I'm doing when I'm in the studio, gives a little more weight to my craft
