I hear you, jcrow! When my daughter moved out for the second time (it's a long story) I thought, oh boy, I can now have a craft room! The other spare room we have is small and used for storage (mostly dh's stuff). However, now that craft room is full of boxes and bags of who knows what and needs a hurricane to come and clean it all out!
When dd and her bunch come for a visit, they stay with HIS kinfolk! I wish we HAD a garage I could turn into a sewing room, but for now, my little sewing corner is in our bedroom.
