I volunteer in a non-profit called Greyhaven Exotic Bird Sanctuary. They help rescued birds to find new homes.
Aside from cleaning poopy cages on weekends, I help them with their fundraising material, such as banners, trifold flyers, and videos.
Recently, I started drawing designs for t-shirts, notebooks, tote bags, etc, so they can have a source of extra income. People do like cute parrots!
The Greyhaven Red Bubble (Merch Design) page is available if you wish to see all the designs.
