If you want to use vinyl, you would need to use something such as the Cricut machine/Cameo to cut it as I read vinyl is toxic if used in a Glowforge. I’ve been doing some testing and found I really like the Engraving Foil from JPP. This stuff is really sticky, the parts I needed to remove from the design was really hard to come off the acrylic and left residue. When cleaning the residue, note that isopropyl alcohol and goo gone can remove some of the color on the brushed gold foil.
I’ve been using my Cricut to cut the engraving foil then applying to the acrylic with transfer paper which turned out to be much cleaner. The vinyl can be easier to work with but does require another machine to cut it unfortunately. There is a lot of testing involved but it is always rewarding and exciting to see what the final outcome is. Have fun!
