I’m sure you’ve seen the IKEA spice rack book holders on pinterest that are so popular that it’s becoming impossible to find them in stock at an IKEA store:
Originally, I was hoping to do something similar, but we couldn’t find them in stock at our local IKEA. While I love the bookends I made a while back for the nursery, they aren’t durable enough to withstand the wear a soon to be walking kid will impart. Instead, I came up with the idea of putting pegs in the shelf at intervals to hold up the books, but keep the spines visible. Since I didn’t want to drill directly into the shelves (the particleboard and melamine combo can be a pain to drill cleanly), we decided to go with the coat rack look.
The wood was scrap from home depot (less than $1), and the pegs were $0.69 for 2. If you’re super resourceful, you could probably pick one up at a garage sale for less.
