“Racing is fun but it isn’t everything. Spending time with friends was the best way to celebrate my birthday! Thank you for coming and for your generous gift.” Send your thanks speeding down the racetrack with this zippy card! The blue color scheme on this 3rd birthday racetrack thank you card design can be changed for you, and all the wording is customizable to your personal style. The back/inside of the card can be left mostly blank (as shown here) or we can print more wording or 1-2 photos there.
