Turn your books into works of art using the Invisible Book Shelf - This is so awesome, I have so many books and I love them all, but storing them on a bookshelf doesn't show how great they are individually.
The inverted bookshelf turns your living room upside down as it hangs all of the books from the bottom instead of supporting them from below. It's a satisfying optical trick and doesn't damage any of the books.
As a kid growing up in Southern California I left at least a few old skate decks in my wake and this killer Recycled Skateboard Shelf from Esty seller Skate Mood would have been a great way to hang on to them and organize the rest of my stuff.
Floating bookshelves, these are bookshelves I like. Looks like you could do this with an IKEA kitchen wall cabinet minus door and turned horizontal to mount. IDEA for narrow wall next to our kitchen wall
