Begin by painting or coloring your plate green. If you're wanting this to be a faster craft you can use markers, crayons or colored pencils. You could also pre-paint plates too and have them ready for the kid to pick from.
Cut out the center of the plate to form a ring.
Trace your child's handprint onto a piece of green cardstock or construction paper. Use that as a template or trace again. You'll want 10-12 handprints.
Using school glue or a gluestick and your handprints to the paper plate ring.
Start adding tissue paper balls or poms onto the handprint wreath.
