The way to make kinah

There is a very popular way to make kinah, and the way is known as doing repeatable quests. However, generally it is also popular to the public as the most boring one, second to grinding mobs for kinah. Your perspective can be changed if you know the right places to grind or the high kinak yielding quest. With that in mind, this can be quite lucrative. 
Another way of making kinah is to craft items with your craft skills and to sell them on the auction Hourse or by setting up your private store. But what you need pay attention on is the number of trial and error as well as research to figure out which items sell best and for what prices.
