Write in the birthday boy or girls name and let me decorate the rest. Then flip this placemat over to draw your own picture. All of our placemats can be used with chalk, dustless chalk, chalk crayons or bright dry erase crayons. To clean, just wipe off with water or use a little dish soap with the water. Each mat measures 12"x17" and has a print on one side and is blank on the other.
