RASKOG carts from IKEA - spray painted after they were assembled using the rustoleum paint in "ocean mist" for the mint and plastikote paint in "cameo pink" for the pink cart. Spray paint some plastic containers to match using a plastic primer beforehand.
What a cute idea for organizing craft supplies. Installing a towel rod with sliding hooks is an easy way to hang small buckets to organize crafts supplies. Storing colored pencils and pens on the wall makes it simple to find the right color!
