: Because Materia Gris is a small character, the pieces will be tiny. Use a precision craft knife (like an X-Acto) and a cutting mat for the best results. Folding & Gluing :
: Apply a tiny amount of white glue or a glue stick to the tabs to avoid making the paper soggy.
: Gently run a dull edge over fold lines to make them crisp.
: Look for a "Materia Gris" or "Grey Matter Ben 10" Paper Craft Template online. These are often shared in .zip or .pdf formats on hobbyist sites like Pinterest or specialized papercraft forums.
