Interesting project! I had to write in Chinese when I cant read/write it at all! I hope my research paid off and I didn't write anything offensive! :) Plus mahjong is a game I observed when I was a child, and hanging out at my neighbours house (Mrs. Tan) in SS2 way back in the 70's! Again, hope my research was accurate enough.
The mahjong chips were made from fondant and the images were hand-drawn; on buttercream icing.
