This may be "old hat" to some, but----
A guy came over yesterday to get some questions answered. One question was: How do you make the Miner's Lamp that you showed at the meeting? This project takes a piece of 1/4" X 3/4" stock 10 inches long. By the time you are ready to fold it up, it has gone through some pretty severe shape changes, which weren't all that apparent to the guy. So I just squished a piece of children's modeling clay into the stock shape and went through the process, using the same tools that I would use with hot iron. It took about 5 minutes and got the point across well.
