A bold multi-color birthday greeting is a cheery way to extend happy birthday wishes on the occasion of another trip around the sun. While you could create a blended look with individual letters, the Happy Birthday Blend stamp set makes it so much easier with pre-spaced letters distributed between four stamps to provide the perfect blend, no matter your color choices, every time. Go for a rainbow or restrict your palette to just two or three favorite colors the results will delight your recipient every time!
