This PVC shoe rack from Cookie Loves Milk is downright genius: Find pipes that are just the right size for your shoe collection (she recommends about a 6" diameter), cut them down to shoe-length, and stack together using pipe glue. Ta-da! It's an endlessly customizable shoe rack—and you can always add to it as your collection grows.
Pick up these crates at Michaels for about $4. Stain or paint. Add a pair of shelve racks from Home Depot and Wa La...you have an attractive storage unit for towels or anything else that requires easy access. (note: Reinforce the crate by securing with screws through the wood into the wall.)
