I don't have a list of deisgns, but I do have 2!
My henna tatoo is on the right and means music, and my sisters is on the left and means dance... I can't remember how much they were each though. They do little designs like ours, but they also do the more elaborate designs!
Once the henna has dried, you can scratch it off and it will have dyed your skin orange (which I have a picture of somewhere, but can't find for the life of me... eek!
...Okay, here's a different one of me, but hopefully you get the idea!

)
Hope that helps
