I am going to have to buy some super glue to keep the mosaics from falling off.  Every time my child opens a drawer or moves it, another sticker falls off.  I am finding the mosaics on the floor, on the table, on my shoe, etc.  It's a cute project and she's had fun decorating it, but I am definitely unhappy with the lack of sticking power.  She's not finished; I hope we are not missing enough stickers to complete it!
