My latest fun find- Chalk board decals. I bought an 8 pack in store at Walmart for about $10. I put 2 in each child's room, 2 on the fridge, and 2 in our master bathroom. You can leave your child encouragement, write love letters to your spouse, or even start a game of tic-tack-toe.
I also bought a pack of color chalk for .47 cents. Get creative! The whole family is enjoying them, even my 14 year old son. They are a bit on the small size, if your budget allows, I would buy a bigger one for each room.
They have a wide selection & design online at Walmart, link -http://www.walmart.com/search/search-ng.do?tab_value=all&search_query=chalkboard+square+wall+stickers&search_constraint=0&Find=Find&pref_store=2177&ss=false&ic=16_16&
