This is so cool. Have you got the henna powder yet? Let me know if you need any help. I have so many henna contacts I could help you getting good powder.
In my opinion the toothpaste looks a bit runny. Usually hand/body lotion is used for practice and it's safe on the skin. Just thought you might be interested in trying that instead, since you have a good hand for henna. Keep it up!!! I'm excited to see more of your creations.
Hugs!!!
