I didn't really have any supplies to use at work, so it's pretty user friendly.
- Just cut a heart shape in a piece of wax paper and brush pink frosting over the stencil.
- You could use a pastry bag with a tip (or even just cut a hole in the corner of a ziploc bag) to do any lettering.
If you want to make your own, I've got a super super easy (and delish!) recipe and instructions here for my Valentine's Day Heart Shaped Sugar Cookies seen below.
Enjoy! :D
