Download Santa clip art and templates (see Materials); print onto white paper, and cut them out. Set face and rectangular coat trim aside. Trace mittens and cuffs onto white card stock; cut out. Trace arms onto red card stock; cut out. Trace belt onto black paper; cut out. Using hole punch, make black-paper buttons.

Glue buttons onto coat trim. Using hot-glue gun, attach mittens to arms, then glue cuffs where mittens meet arms; let dry.

Repeat until entire body and beard are glittered (do not glitter face); let dry. Glitter both arms, front and back, except at the inner top area and inner mittens, where each arm will attach to body.
