We have four bedrooms, I use one of the spares for my sewing room and another one for the quilting table, because it won't fit in with all the other sewing furniture and ironing board. Hubby has his tread machine in there with the quilting table, so I cover it up when I am not quilting. I suggested making the other spare bedroom into an exercize room, but he won't give up the guest room. Dog-gone it.
All that being said, I do handwork in the family room at night while watching tv with dh.
