I sat in my room, staring at these as they were perched on top of my clear block. After a few minutes, I saw "the eyes of a pumpkin", so that's what I did. The pumpkin is made from the Paper Pumpkin Business builder set we were able to purchase at convention. The leaves and back ground are from the Project Life Calendar Kit stamp set. A quick squiggle of my fine point black marker, made the mouth.
I will continue my quest to find more ways to use these lonely antlers. Unless of course, Stampin' Up! has an image all set for us, to go with them, someplace in the warehouse. :-)
