Have had Zazzle complete a number of T-shirt projects in the past. This one had several design elements. It was well done. I will work with Zazzle again.

Our Girl Scouts were bridging to adult and our troop dad was always there to lend a helping hand. We wanted to do something special for him so we put special pictures on the front and a note on the back. It brought a tear to his eye. .
