For Christmas I made my daughter a tea party play mat. I got the idea here http://xxsweetfancyxx.blogspot.com/2009/08/coopers-tea-party.html
The tea cups are open at the top so she can put in a play tea bag (made of tulle and felt scraps). The cookies, plates and tray all have velcro so they can be moved around. This project was so much fun and I am looking forward to adding more pieces to it.
