How do you start a project? Me, I typically start with a thumbnail sketch and depending on if the project is complicated and involves expensive or one-of-a-kind materials, might make a prototype/model out of a cheap material to make sure that all the angles and parts work together. Right now, I’m working on a tutorial for an etched dichroic glass bird house with a copper roof so here’s my prototype out of foam core and thin aluminum. The pieces all fit so now it’s on to cutting the glass and copper. I’ll post more pictures as the tutorial progresses!
