As for my part, I have been collecting and smoothing out old wood planks for my old, re-kindled interest in an old hobby. I used to burn wood with imagery like old west themes, flowers or fantasy creatures. I know, not much overlap there, but it is the wood burning that is the "art" and I have recently done a few different things and found it just as engaging as it was much earlier.
I enjoy it!!
I took an image from my fractal art and tried to burn one and everyone I show it to thinks it is amazing, but I think it sucks, but I am not quite ready to give up just yet. Absolutely everyone doing wood burning seems to follow some theme or other, but I have not seen anyone do just plain abstract imagery for depth's and shadow's and light's and mystery's sake.
Does EVERYTHING have to be a picture of something recognizable?!!!?
