Build the face and pads flat
Draw the face mask, belly, eyes, ear crosses and foot pads on 2.5 mm graph paper, one square per pixel, and cut them out as templates: the mask about 16 squares wide and 12 tall with notches for the eyes along its top edge, the belly a stepped oval about 16 squares wide and 18 tall. Roll blue, yellow, white, red and black about 1 mm thick (between two stacks of three playing cards). Build the face flat on parchment: cut the mask from blue, cut the eye and mouth shapes out of it with the tissue blade held upright, and drop a yellow eye and a white mouth piece, cut from the same templates, into the holes, so they sit level instead of stacking up. Tap a small red cross into the middle of each eye, a stepped black nose above the mouth and a thin dark blue line across the teeth. Build each foot pad the same way: yellow, with white toe marks dropped in.
