I just started trying to make some shields. I've been using foam flooring (the interlocking puzzle pieces) and foam board. What I'm wondering is if I am required to put two layers of foam flooring together? Currently I'm thinking I cut the flooring into the shape I want the shield to be, then cut the foam board so that when glued to the flooring it leaves at least 5/8ths of an inch of foam on the edge. Is this an okay construction method?
