Among the fascinating customs of Kuruba Gowdas is also the use of Hatti Kankana(ಹತ್ತಿ ಕಂಕಣ) and Unne Kankaka(ಉಣ್ಣೆ ಕಂಕಣ ) during marriages. In fact all Kuruba Gowdas are split into two groups depending on which type of thread they use during their marriages. Most other costums and traditions remain the same between these two groups.
"Hatti" is cotton and "Unne" is wool from the sheep. Kankana is the the thread made with either of them and which is tied to the wrist of the groom and bride during their marriage ceremony. Usually the marriage is between the same group of people, that is the Hatti Kankana followers marry the followers of the same custom and vise versa. But in modern times this has not been strictly followed and marriages between Hatti Kankana and Unne Kankana people are common.
The story behind this custom and division of Kuruba Gowdas into two groups goes back to the ancient times many thousands of years ago. An ancestor of Kurubas called "Padma Gonda"(ಪದ್ಮಗೊಂಡ) had two wives, the first wife was a Kuruba Gowdathi and the second wife belonged to the brahmin community. So Padmagonda decides to marry off the children born to his first wife by tying the cotton thread to their wrists and he marries off the children born to his second wife by tying the woollen thread to their wrists, thus heralding the formation of this custom.
