This idea sounds sumptuous and fun!
I wondered if there were instructions on the internet and I found these on instructables.com that walks you through the steps, with pictures, to trace a picture using chocolate as your paint. http://www.instructables.com/i...-CHOCOLATE/?ALLSTEPS
Reading through it the materials used are:
- Wilton Candy Melts
- Ziploc bags
- Wax paper
- Tape
- Small painting brush
- Toothpick
- A photo or a drawing
- A container to hold hot water
