Cut just inside the black lines if you can.. use one scissor blade to scrape the rest of the black ink off. Or, use the draft setting on your printer so the lines will be lighter. The ovals at the bottom of the pattern are to allow the deer to stand up. Put the tabs on the bottom of the reindeer's feet through the slits in the ovals then fold the tabs and glue them to the underside of the ovals.
Score the dotted lines. The slit in the neck of the head pieces as well as the slit in the top front of the body need to be cut a little wider. Do not cut the head slit wider or the antlers will slide out.
Put a dot of glue inside the tail.
