RE: How to store foamys???
I have somewhere between "don't you have enough" and "Oh my god! Open your own hobby shop!", in my hanger.
So, I have limited space also. What I did was bought the hooks with the plastic coating to hang bikes on and started hanging them on the wall(s).
No pictures hanging in my office or room. My wife can't stand it, and I was told the living room was off limits. Lol.
I have most of them hanging vertical, flush with the wall. It abled me to hang more than if I hung them from the ceiling.
Hope this gives you at least one idea.
