You are definitely not alone. Been there, done that, sewed up a storm on the coffee table for years. Though I have a dedicated studio (my son's living room) and enjoy it. The funny part is that while I have a good-sized room, with design wall large enough for a big quilt......I still spread out to two other rooms! And then have to clean it all up before anyone comes. My son hung curtains in the archways so that people coming in would not see into the work room. Too funny.
Hang in there and keep sewing and quilting!!
