I love these shelves.
All I did was:
Cut up some closet shelving to the size I wanted.
Put 4 ring hooks in the ceiling.
The "ropes" are 4 small dog leashes I bought at a $1.00 store.
I sewed in loops with clip style curtain hooks inside.
The curtain hooks clip onto the shelves and are amazingly stong.
They can be easily taken down because I left the original dog "slide-lock hook" on the leash.
(see improvement update on Mods page 7)
I cannot take credit for this mod, but I cannot remember where I saw it, so sorry If I don't credit the original inventor!
Bunk Headboard...covered with carpet!
The first time we used this, slivers of wood kept on getting on the mattress. It's fixed now.
