All you need are:
1. Onesies (as the "cupcake")
2. Baby socks (as the "cherry" on top)
3. Cupcake liners
4. Cupcake box (optional - you could just use a regular box)
It's quite easy so don't be afraid! Step one: fold the sides of the onesie to the middle.
Step two: fold bottom over the top so it's half as wide.
Step three: take a sock, fold it however you like, and starting at one end of the onesie, start rolling it up.
Step four: place your onesie in cupcake liner.
Ta-da! See, I told you it was easy! Do this for however many onesies you have, put a ribbon on the box, and you're good to go!
