From the project
Small projects not worthy of dedicated repositories
Etsy.com. Lots of amazing looking products. Mostly rings,pendants. Pure resin or resin+wood. 200-400 NOK. Sometimes glow-in-the-dark. Resin 'stone' with wood base, silver ring inlay. 700-800 NOK.
Maybe silver + resin cast rings has good opportunity? Not found, might be able to push price up.
Oxididation. Electroetching with laser-engraved masks?
Power board for wearable or other battery powered electronics.
