Haven't seen anybody mention hanging stuff so will toss this onto the heap:
Large cup hooks are good for screwing into walls and ceilings to hang things. Two strategically placed above the head of my bed to hold the solar lantern for reading at night. Several in the ceiling, parallel with the wall, above the "kitchen" area, got a cafe style curtain rod, hung it from the cup hooks, used S-hooks on the rod to hang various items, a net/scarf hammock for bread, produce, etc. Also ran a rod across the back for small items (underwear, socks, gloves). Keep it close to the walls so you don't hang yourself on it.
I used scarves to make hammocks for stuff. Tie a knot on each end and there's your hammock. And they were pretty.
Best wishes.
