Mine is closet-size, so not exactly comfortable or inviting at all. I sewed in the lounge (dining room / living room) a few months ago while there was work going on in the house and loved it, but dh hated having my clutter appear in his space so I had to go back.
I need more surfaces to keep things on, there's only my cutting mat and ironing board since the machine takes up its table, so naturally everything has to move to one surface when I have to use the other. Chaos is the result, and not the organised kind!
