Use popsicle trays to keep crayons sorted.
Containers and labels can be bought at the dollar store to keep everything organized and looking pretty too!
A dish rack serves as a storage area for books, files and pencils or markers.
Plastic cups in a muffin tin act as an art supply tray.
Keep sharped and non-sharpened pencils in separate jars.
Here is an idea I love, DIY Dry Erase Boards using picture frames and paper from the dollar store!
I LOVE this idea and I am going to use it!!! use a dollar store map with a bookcase you already have and look at this!
