I've almost finished making the Kama for my Akali Bloodmoon cosplay. The only problem I have is where the "blades" (made with foam board) meets the handles it's a bit... floppy? I'm afraid that it'll break during the convention.

Is there some sort of material I could use (a particular type of spray foam, or something else/better) that I could apply to the props before painting to make it stronger?

I've been told that a two part epxoy resin would work but online it's only available from abroad (it doesn't seem to be sold locally) and is mad expensive.

Thanks guys!♥
