Each project takes approximately 40 minutes to complete with students. They are super easy prep and the skin tones and hair can be changed on the elves easily for whichever skin tones match your students if you desire. Simply print on the correct colored skin/hair or print template onto cardstock and trace hair onto different colors for each student. I have done both and they enjoy each. However, they seem to really love having it match them (but this is more work though).
