Foam
I mainly use 3mm thick foam that comes in 12×18 inch sheets. 5mm thick foam is great for belt pouches and other simple shapes that you want to be more sturdy, but it can be difficult to cut complicated curves out of. 2mm foam can be great for intricate detail pieces. (In general, the thinner the foam- the easier it is to cut, the thicker- the harder. 3mm thick is best for most of my items.) Also popular among costumers who make thicker armor pieces are interlocking exercise floor mats, which can be found at most hardware stores. For making the items found on this site, I recommend that you do not use foam that is thicker than 5mm, as it is simply too thick beyond that point to cut out small shapes smoothly and cleanly with scissors, and knives don’t work well for tight curves. Note that you can always cut out several layers of thinner foam and then glue them together to make thicker pieces.

Glue
I use a variety of super glues for most of my projects. Rhino Glue is a great all-purpose super glue, I also like Fastcap 2p-10 (also try out their extra micro tip nozzels), and the Krazy Glue brush. Also popular with foam fabricators is contact cement and hot glue.
