This whiteboard made from household materials works like any other- and you can make it in any shape or size you choose!
Cardboard (cardboard with white on one side works best)
1 Ziploc Storage Bag
Dry Erase Markers
Step 1: Cut your Cardboard
Measure, mark & cut your cardboard.
Mark the dimensions 8.5" x 11" -the size of normal printer paper.
After cutting your cardboard with an Xacto Knife or similar cardboard cutter, if you are using cardboard that's brown on both sides, glue or tape a piece of blank white printer paper to one side of the cardboard.
