*There's no strict requirement on how much of each color to use, but I think they look the most natural when you use mostly white. If you're making more than 13 of these seashells, adjust the amount of chocolate you use accordingly. You can easily store leftover melted chocolate in a plastic baggie. It'll harden, so you can just remove it from the baggie, place it in a microwave-safe bowl, and easily melt it again. [br]**If you use red candy melts, you can mix them with extra white to make a pink hue.
