The bat wings were kindly provided in a collage sheet from jackandcatcurio.com. I used Diamond Glaze on them which made them curl, then crack as I tried to straighten them. I didn't plan it, but they look good all crackly. The tree branches are transfers, also from a jackandcat collage sheet.
It was a fun card to make, and I've got a few more Halloween-themed ATCs in the works. What a great time of year for art!
