Playing off the common idiom "make the world go 'round," I have used this saying to express that cats are important to all people around the globe. The t-shirt is a fun wearable way to advertise Willo Beach Sanctuary to passersby. T-shirts could be sold online as a donation or brought to events for others to purchase or as a freebie to pass out. T-shirts offer a passive advertisement without pushing the organization's agenda too heavily to the audience.
Here is a postcard that would be sent to previous supporters of Willo Beach Sanctuary as an added bonus, with an example of a success story of Morrigan. The postcard is meant to more personal than many other collateral materials to entice supporters to share with their fellow cat lovers. It shows how their proceeds go to helping cats in need.
For Willo Beach Sanctuary, it is important to get information out about TNR practices. This information would presented in a printed tri-fold brochure for people to carry with them and read in their own time. The imagery would be animals who have success stories through the help of the organization.
