My lovely DIY shelf in my guest room using 4 crates stacked together! Simple edge-paint project that ties the colors of the room together immediately. All my guests compliment it all the time. It is very sturdy and holds heavy books to sweaters.
Had when i worked in a preschool and kids love them! I would use colored sand instead of white salt. DIY salt tray with alphabet cards. Easy to make and kids have fun smoothing out the salt after correctly making the letter
Crate Storage: Wooden crate converted into a portable side table with storage - love this creative idea. Easy to make: Turn crate sideways, add a couple of internal dividers & screw 4 castors on the base. wheels for me)
