Yay! I finally tried henna on my own hand. Here is the result.

My whole arm

And the back. The character says "Om"

Took me 1 hour to draw the pattern and then i wrapped up my arm(using medical tape and a long sock) and let it soak into my skin overnight. The colour is supposed to darken over the next 2 days, but I dunno if that's true.
