I went out and bought an electric pancake griddle and a heat gun that very day. The next day, I went to SF and got plywood from Discount Builders Supply, 5# of beeswax from Douglas and Sturgess (that'll last a while) and encaustic gesso from Dick Blick. Now all I need is Damar resin.
I can see how one could get very meticulous and "crafty" in terms of the technique. It seems like it could be very "Zen"and addictive--something that I could be doing into the wee hours.
Here are the 2 pieces I made at the workshop.
