Hi Ruth, I went to a belly-dancing party on the weekend and there was a Henna Tatooist there. The henna that she used is just the henna powder that you can get from the markets. You mix it with some warm water so that its the consistency of toothpaste and get the lumps out too. She then put it into a tiny little piping bag made of clear plastic with one corner cut off for the paste to squeeze out of. Too easy! You leave the design on until dry (about 1 hour) The paste will flake off easily and then its done. We had loads of fun!!!! Mine is still on after 4 days.
