I'm lucky in that my son's bedroom is the largest in the house and I have it for my sewing room. It is jam packed, but organized and it is my favorite room in the house. He could never move back home, it is my room now.
I keep a small TV tray by my chair in the living room so that when we watch TV at night I can do any hand sewing. Try to keep it neat as it bugs my DH if I get too much stuff on the tray.
