I've actually never done this, so I'm sure there are other, more sophisticated ways of doing it. But these are the materials that worked for us:
Good old Idaho pataters, cut in half. These were the perfect size for my kids to grip. I used the ballpoint pen to etch the designs into the halved potatoes, and the strawberry huller to remove the potato flesh around the etched shapes.
We decided to do the first letters of the boys names:
I also did a batman logo because I'm an awesome Mom (or I'm feeding into their obsessions...whatever you want to call it).
We had lots of fun, and used some spookier "batman colors".
So if you have an abundance of potatoes in your pantry, and some easily entertained kids, you'll know what to do.
