Author Emma Thomson’s Friendship Fairy Felicity Wishes is the latest brand to join Digital Giving’s charity app, “T-Shirt Booth.”

The app allows users to create personalized t-shirts featuring their favorite characters with some of the proceeds going to charity.

Proceeds from Felicity Wishes t-shirts will go to the charity Dreams Come True.

Other recent character additions to the app include the preschool brand Monkey Music (for the charity Nordoff Robbins), Punky Princess (for Kidscape), Green Arc Creations’ Curious Cat’s Way Out (for charities helping endangered species) and Bagpuss (for Hospices of Hope).
