After using the room a while, I have a better feel for it. Things are getting organized slightly differently. And for sure I NEED a permanent design wall.
Stash will be going on these shelves below the design wall. They used to be one on top of the other on the opposite wall. Now I've moved a different bookcase there. Now that the furniture is where I want it, I've started hanging things on the walls. Stay tuned for more pictures later this week. Neater, hopefully!
