Step 1: To Get Started
Oreos - I like to buy the family pack (shown) or the real big package from Costco because they have individual sleeves you you can kind of customize the portion you need.Meaning if you only need 10 Oreos you dont have to eat the whole package before it goes stale. And it is cheaper too.
Red Chocolate Melts- I buy these from Michaels http://www.michaels.com/Melts/products-bakeware-candymaking-melts,default,sc.html
