Step 2: Prepare Your Drawing
The first thing you're going to need is a drawing to trace. I happened to luck out, in that I hang around with a lot of talented artists. My friend Travis donated his skill to this particular project.
If you don't have access to any friendly artists, you can probably find lots of pictures on the internet to use.
The important thing to keep in mind is that all the lines have to be connected somehow, and you don't want to go into too much detail. Remember that you're gonna have to follow these lines with chocolate! My experience is that straight lines and gentle curves are pretty easy to trace, and sharp angles and curves are easy to trace, but slight angles are always gonna come out looking like curves.
Once you have your drawing, slip it into a clear sheet protector, because if you're anything like me, you're gonna be getting chocolate everywhere.
