If I'm piecing blocks, I'm at the small desk in our bedroom (bought it when I was in college umpteen years ago). When it's bigger work, I kick the family off the dining/kitchen table (this means "picnics" in the living room for the kids).
Ironing - in the kitchen where there's a counter to sit the hot iron so it's not taking up precious ironing board space.
Layering - back to the kitchen table.
My kitchen table is fantastic. Almost 7 feet long and 42" wide. Hubby made it to fit our brood around. It's been nicked and scratched and has two small gouges from him dropping the power drill on it - twice.
We live around that table.
