I made this video a little while ago talking about what you can or can’t use in your glowforge including the new aura. Short summary is anything that is true vinyl you should not use in your Glowforge. And the eco iron on proofgrade you can use because it doesn’t have vinyl in it.
I seen more questions about this so I figured I’d share this video in the everything else category since it contains non proofgrade info in it: https://youtu.be/SXQg5iFR9Ng
Hopefully this helps clear some things up between the two.
