I was shopping for a gift for *ahem* someone else when I was pulled into the shop Gloss at the Lab by their rows of prettily displayed clothing and accessories. The real standout was this wall of display shelves crafted from vintage books.The shelves at Gloss were suspended by simple "L" brackets (not seen above), and I was able to find a DIY tutorial for a similar project on Real Simple. The only modifications that I would make would be to glue a few of the pages to the top cover so that the book can be oriented forward and open. I would also replace the top "L" with a flush mount anchor affixed to the top cover of the book and the wall.
Let me know if you decide to give this a try and how it works out!
