I've sewn in lots of places...because I take handwork with me where ever I go.
"In house"? I have a sewing room where I have my Janome, Singer 201-2 and my Huskylock serger set up. My Singer treadle and Kenmore are both in my dining room, and the Wheeler & Wilson treadle is in the living room....I've yet to make anything with it yet tho!
I'd love to have a porch or deck to sew on!
