This birthday photo thank you card can be customized with any border color you like (although pink & blue are the most popular) & can be single sided on photo paper with a soft photo in color, black & white, or sepia. Pair with our Pink, Purple or Blue Birthday Photo Invitation for an adorable set. To showcase more photos, create a double-sided flat design on card stock with a photo collage on the back (with an accent in the middle of an initial or graphic), or even on our folded four-panel cardstock for additional wording & photos. This design is also easily adapted for any age or another event, see our Pink First Holy Communion Photo Thank You as one example.
