Tasseography or tasseomancy is still the same word for tea leaf reading but I did not use tea leaf due to a oracle deck called "Tea Leaf Fortune Cards."
The only thing I did know that you can use it with tea leaf or with coffee, but I had no idea you can use it with wine. It makes me think in what other beverage can you use it for. Makes me want to experiment! XD
I had tried it with tea leaf and so far I got a clear picture of a snake, an arrow, an umbrella, a beetle, and a fish. At first I had trouble looking at the beetle, but than I had to examine in all angles and voila it was a beetle.
I did had to check the tasseomancy book, but it was a lot of fun.
The only tip I can tip of is that you really have to examine all the angles of the cup to get a clear picture. :D
