Hi RPF folks! I've recently been trying to make various foam items such as magnetos new costume and some iron man parts and I've faced a few problems that I need help with. The foam, whenever I cut it, has fringes and I can never seem to cut a straight piece of foam. This has been very annoying and hard to look at too. Also thing such as magnetos horn part are small and feature slants and I was wondering if any of you guys knew how to make such slants with foam. Thanks for you time!
