I have been there! I started quilting after my kids were all gone from home so I turned one of the bedrooms into my quilting space-one year and 2 granddaughters joined the empty nest. One got the quiling room and I moved my 3 machines into the dining room and my stash and UFO's where ever there was an empty spot. Now we are once again empty nesters/have moved and I have a quilting room again. Peace!
I never sewed in the bathrooms though, there was always someone in them.
