Begin by painting or coloring your brown. If you're wanting this to be a faster craft you can use markers, crayons or colored pencils. I've been loving these stick paints too! You could also pre-paint plates too and have them ready for the kid to pick from.
Cut out your antlers, reindeer 'face' and glue onto the plate. If you're having trouble securing the antlers to the back of the tape with school glue or a glue stick you can use tape too!
Add your googley eyes (or drawn ones) and a red nose if this is inspired by rudolph. Completely up to the kiddo's creative direction. :)
Add in details with marker or crayon for a smile, eyebrows, etc. Display on a fun bulletin board or use as a temporary wreath!
