The pattern will be at the end of this post for the head and other pieces that I used, but here’s a chance to be super creative and make up other parts and make other fun characters.
Some suggestions would be different hair, hats, noses, animals, celebrities (real or fictional), whatever!
Then show us your stuff! Please share the pattern for any new add-ons so that we can try it out if we want to.
P.S. this pattern only takes a couple of hours, start to finish. 
Now, the pattern:
