For the past two years, the kids and I have made little heart shaped crayons for Valentine's Day. They are easy to make and the kids love unwrapping the crayons and breaking them.
I use this pan (used my 40% off coupon off at Michael's), old crayons (Crayolas work the best), a low temp oven, lollipop bags, ribbon, and print outs the following poem (this is just what I came up with):
with swirls of colors - red, pink, green and blue
In the shape of a heart for Valentine's Day
So draw, draw, draw whatever you may
This year we decided to do something different. I found some cute pencils at the dollar store (12 for $1) and with a paper heart, some heart stamps, stickers and a pipe cleaner, they became butterflies.
