You finally made it to the store, and the Valentine's Day shelves were completely picked over?
No problem. Here is a homemade, candy-free Valentine's Day card and rainbow-heart crayon you can make tonight with stuff you either already have - or can get your hands on pretty easily.
You'll need: Crayons, a knife, silicone baking molds (or just a cupcake tin), card stock, scissors, and double-stick tabs or rubber cement
Step 1: Peel the paper off your crayons, then cut them up with a knife - I went for about pea-sized. For me, it took 20 full-sized, regular crayons to make each batch of 14 heart-shaped rainbow crayons. Rose Art was easier to cut than Crayola.
Step 2: Mix up the crayon pieces and drop them into your molds. Fill to the top, without letting any pieces hang over the edges.
Step 3: Bake. You can find lots of instructions online, but here's what worked for me. Since I was pretty sure the molds I bought weren't intended for baking - and certainly not for melting crayons - I wanted to be on the safe side. Once filled, I placed the molds into a cake pan with a water bath, then baked at 200 degrees, checking every 5 minutes until the crayons were thoroughly melted. Fifteen minutes wasn't quite enough, and 20 was just a hair too long.
