Henna Tattoo

Anyone like Henna Tattoo??
They are like tattoo, but it will fade about 3-4 weeks time. Nice to draw on for some functions.
I know Malaysian Hindu wil draw them during their big festival.
I love them. Looks cool~ Love the pattern and looks of it.
But I don't know how to draw them. I try to buy the indgrediants from Little India in Penang, but never used it.
