I do not have a craft room in my house. A few years ago, I started to move totes of yarn upstairs, on shelves on one wall of the "gym" room. I have always used our walk-in closet for such items, along with shelves in my utility room.
I have started the process of cleaning it all out of the closet, and oh my word, did things get buried in there. I have used a bookshelf full of crafting items. I am attempting to empty it, come up with an organized storage upstairs, and move the bookshelf to the "guest" bedroom or spare room.
