Last year my daughter made these peppermint heart Valentines. I believe I got the idea from Martha Stewart but I'm not sure. But they are simple to make. Take your leftover candy canes and arrange them on a baking sheet with a silpat mat or another nonstick surface. Place them in a 350 degree oven until they start to melt and run together. Don't let them spread out too much. IMMEDIATELY pull them out and stick a lollipop stick (you can get them at craft or candy supply stores) at the bottom. Let them cool and then they come right off the mat.
My daughter made her own little tags as you can see and slipped them on the sticks and then placed each one in a ziploc baggie. I will warn you that they are VERY brittle and will shatter easily so carry them carefully. Great way to use up old candy canes, do a craft with your kids AND have unique, handmade valentine suckers!!
