First cut the center of your paper plate out, leaving a ring for the wreath. Discard the center of the paper plate.
Next you {or your child} should tear/cut up the green crepe paper into squares.
Now put a good layer of glue all around the the paper plate ring. Have your child place the crepe paper squares on it, until it's completely covered.* Once that is done, have them glue some red pom poms all over the wreath. Set aside to let it dry completely.
While that is drying, trace your child's hands on the red cardstock. Trim those trace-outs out and staple them together to look like a bow.
Once completely dry, staple on the "bow" to the front of the paper plate Christmas wreath and display the finished piece proudly for ALL to see!
