I'm making a mask using predattack(?)'s huntorial, but when it comes to actually cutting details into it, I'm doing incredibly horrible. First, it's hard to cut it without leaving a bunch of chunks and an overall unconvincing texture. So before wasting any more foam, I was wondering if any of you guys could give any advice about it. Like, for starters, what tools are the easiest, if there's any sort of technique to cutting foam, or anything that can help.
