This listing is for one set of 6 holiday cards, all with the design shown above. The design is a beautiful watercolored blue circle (reminiscent of a world?) layered with snowflakes. The phrase below says "let it snow", and the final touch is a small sparkling blue gemstone. The cards are blank inside, and come with six plain white envelopes. The cards measure 4.25" X 5.5", (with the envelopes measuring just a touch larger), and should take a regular USPS stamp. If you are interested in a custom design, please let me know, we can create something just for you!
