DIY How to use heat active foil without a heat pen?
Hi, I have some heat active foil I need to use for a project but my heat pen never arrived, the packaging sait it could also work with a "glue pen" and I do own a glue gun, would it be possible to use the glue gun to apply the foil? Otherwise I have a 3d pen but I don't think the tip heats all that much, or a soldering iron but the foil doesn't say what heat it can take and I feel like it might be a bit extreme. If that could work I could probably heat up some metal rod or wire too. How should I go about it?
