Living on my own, I have two spare bedrooms. The single is left for friends who often stay over and the double is mainly for sewing. Ikea have office type table tops with separate extending legs that fit over the width of a british double bed so without using any more space in the room, I have a cutting table. A second one with separate drawers underneath is in the bay window for sewing and I use the two wardrobes for storage. The ironing board lives in this room too.
On the rare occasion I need the double for guests, I just tidy up and the bed is free. The table over the foot of the bed is no problem because it is tall, but it can be moved or even dismantled if needed.
My Featherweight lives in its soft bag under the hall table. Ready to be put on the kitchen table for mindless sewing or taken out for classes etc.
Luckily there is no conflict between guests and sewing for me.
