Hi Ben!
In the How to Not Fry Your Object video there is a scene of you prying/cutting apart hot glue. There is a super easy way to remove hot glue from projects. Use a q-tip dipped in 91% Isopropyl Alcohol and swab it around the glue where it meets the object to remove and where the glue will be removed from. The glue should then easily peel off.
I have tried this on metal, plastic and even wood and it works a treat! It should work on fabric as well, but I have never tried it.
Just thought I would put this here just incase you or anyone else who (like me) loves using hot glue in their projects.
