She wore it to the airport when we picked up Jeff, and he insisted he wanted one as well.
I guess maybe we should have done a little tutorial, but this isn't a project I necessarily want to do again! However, as I recall, here are the steps we did:
Buy two sweatshirts in the color and size you'll want to wear. Michelle picked gray for the elephant part; that only uses half the sweatshirt, so there was enough for the second one. On both sweatshirts, cut off the sleeve that you want to become the trunk. (Michelle chose the left sleeve, and Jeff the right.) Find - really, create - an elephant pattern and use it to cut the shape out of the gray sweatshirt. Appliqué it onto the main sweatshirt. (This is the part that Mom did.) Then sew the gray sleeve back onto the main sweatshirt. Put on the finishing touches using fabric paint. (That's where the paint comes in!) Wait for it to dry before you try wearing it.
