I did a google image search for "couple silhouettes" or something. We found one we liked, that looked simple enough, cut it out, traced around it, and painted the inside of the outline.
There are other really cool things you can do with the crayons, like this one someone did.
I honestly have no idea. I don't know much about art or how to best protect it. I hope someone with more knowledge answers you! These are the ones that inspired me. :)
I just made a standard chocolate cupcake recipe, frosted them with store bought frosting and then made the churros. They weren't that complicated at all.
For the churros, I used half of the batter recipe. Then, instead of using a decorating tool, I just made little hand rolled snakes and fried them up in a deep frying pan of oil.
