I did two back-to-back holiday-themed fundraisers one weekend in 2014.
The first was with Santa (AKA the father of one of the shelter employees). It benefited Weber County Animal Services. The second was at Petco and it benefited Black Dog Walk. I purchased and put together the back drop and props, photographed the pets, retouched the photos and designed the fliers as well as social networking and emailing customers their finished photos.
I had to photoshop the background since my backdrop wasn't wide enough for a group photo.
This guy was at the shelter waiting for a home, and he did NOT want anything to do with Santa. :)
