this small wooden staircase also works as tiny closet (via Design*Sponge) could be used in tiny house design in place of ladder?
Craft space organization: If you only have a closet or a small nook (could be covered by a pretty curtain or doors), this is an awesome way to get organized - the rolling cart is at IKEA and the white boxes to the r/h side are from Michael's - often at 40% off. The ribbon/etc holder also from Michael's, but would be easy to build and probably more sturdy.
Shelves attached to the inside of a closet door for shoes, purses, scarves, wrapping paper...or whatever your heart desires.
shelves attached to the inside of a closet door... Shoes....purses.... awesome! I especially like how it has a stopper in front of each shelf...so nothing flies out or around when u open the door!
