I have been experimenting with cutting felt. I am using both 3mm and 5mm 100% wool felt. In order to get the laser to cut through I’m getting a dark burn mark. The char will flake off but still leaves a noticeable discoloration. What can I use to clean it off?
I have also been experimenting with engraving felt. Since the char will flake off, it needs to be sealed. I found that both clear acrylic spray and gum tragacanth will work ok. Anyone have other suggestions?
