I am bored and have no faith in humanity. So..Want to attend a free demonstration and exposition of steel etching without acid? You can tip me if you want or care but I will write up a cool handout, get the proper chemicals for safe etching, and we can etch some steel together so you can use it for printmaking, jewelry, or whatever. I'm just a technician, I don't understand what creativity is anymore.
I have my own vinyl cutter to make resists, when I taught official classes in the past we used vinyl, paint pens, all sorts of things. I can take .STL files and we can make your own designs.
I am thinking a saturday night in the next few weeks would be fine. I can't be assed to set up an official class so we'll meet wherever we can find a spot. I'll wear a silly paper crown or something so you can find me.
