Maybe something like butterick 4677, a storage ottoman, would be a good option? You could put a decent amount of crafting stuff in it, and it would work as a place to sit while you craft.
The thought that I had when I first started reading was that it would be really cool to do something like paper dolls either on the walls or on a dividing screen. When I say paper dolls, I actually mean like a fashion croquois (model) where you could try your design ideas by making smaller versions and "try them on" the models on your walls.
Wow, that was a really horrible explanation. The original idea came from two books that I've been considering buying for my 12 year old daughter: Paper Fashions (by Klutz), and Casual Chic by Jayne Miller. They both come with stencils for making clothing designs without drafting skill, and I thought it'd be a fun idea to do something similar to the stencils on your walls, but ideally it would be better if they were bigger than the ones in either book.
Hope this helps!
