Recycling is always a good thing. Wanting your kids to eat all of their valentine's candy just so you can use the box is just wrong but it works for me. Take 2 used Sweetheart boxes. Wrap with clear packing tape (for rigidity). Punch various hearts out of cardstock. Write facts and opinions on them. Put an "O" or "F" on the back (for self checking purposes). Voila! You have a lovely center that the kids will love to play over and over again. (Click on the image below for a larger image.)
Happy Belated Valentine's!
