According to Are questions about LARPs on topic? LARP questions are OK here, as LARP is a subset of role-playing games. But the question I want to ask is more about DIY techniques than the very act of role playing. I would ask it on a DIY stack, but sadly https://diy.stackexchange.com/ is now called Home Improvement and such questions would not be welcomed there.
Question I meant to add: What are easy to apply latex alternatives on foam weapons? with description of what do I hold against using latex.
