Shirts like the above at TeePublic. Red is traditional, but I have enabled a few complementary colors, in case you would like to stand out from the crowd. It’s got a kind of Jayne-like vibe to it, I think. The big text says “Spring Festival” in Traditional Chinese.
These cards have the added text “恭喜發財,” which is the common “Gung Hei Fat Choi,” loosely ‘Congratulations and be prosperous.’ They are totally blank on the inside, but the back is branded by Zazzle. Additionally, Zazzle will let you add text to the card before purchasing, in case you would like to put a typeset message inside your cards.
