So, I'm very, very new to cosplay, and I really just want to dive right in. I've been tasked with making props for both me and my brother's cosplay, but I'm not quite sure what materials I need to make them. I've bought two items to use as the base for the props, but I want to know what items(i.e. specific paints, fabrics, materials, etc) I can/need to use to alter them to look like the weapons the characters are using in the references I've provided below. I know a lot of people use craft foam to make their props. Would that be appropriate for this project. Also, below the reference pictures, I've provided an attachment image for the bases I'll be using. I apologize in advance if I'm not clear enough, but I would be very grateful for any information you can give me. Thanks for helping a noobie out.
