I have all my yarn in bins in a small spare room. I’ve seen walk in closets bigger than this room. We have an old desk in there and I have my swift and yarn winder attached. It works. I keep a bin of useless balls of yarn that I eventually make into a scrap blanket. I’m probable due to make one this winter. It’s those useless balls of yarn that take up a lot of space.
All my too big/once a year kitchen stuff is stored in the basement.
