We got this idea from Family Fun magazine. We don't usually actually make these ideas we see, but I told myself 'since we're homeschooling, we have time for this, and it can be a little art project.'
So we did it, and they turned out great. The kids had a great time, and are very proud of our creations.
Oh, so Ben's is Frank (notice the bolts in his neck!). Matthew's is the Count. Abby's is the Witch. And Emily's is the Mummy (we did hers for her).
