I took over our daughter's room when she graduated from college - in 1986 and it is truly all sewing. It had a bed in it for a while, but we no longer consider it to be a guest room. Too many pins in the carpet.
Last year we did a make over when the college discarded lab benches and glass front cupboards from the Physics lab. Lots of wonderful storage for me, but I am starting to leak out into the hall. Think I need to perform some stash reduction - in other words get busy and sew.
