Although I haven't used the kit yet,I have found that the book has put me at ease and makes me feel I can do well even without much experience.The chapter about making your own henna explains what the catylist solution is and what its for.Read through it thoroughly and you will learn all the basics to start.More information than I expected from a kit.
This kit was my first experience with henna and I was extremely excited to get started. However, I was disappointed in several ways: 1) even though the cone applicator is traditional, it is extremely difficult to use and for a kit that is promotes almost 'instant' tattoos, some alternative should have been provided; 2) the henna paste was ineffectual -- I tried several times on both myself and my sister and only got faint results; 3) knowing far more about the henna process than I did when I bought this kit, it seems that the instructions are missing steps -- for example, the instructions say to let the henna dry for 1/2 to 1 hour and then scrape off the henna, however every other book I've read says to leave on the henna overnight or as long as possible, plus there is no mention at all of the lemon-sugar solution every other book mentions. I will say that the designs in the book are very creative and there is good information on how to select fresh henna. However, I would not recommend this kit at all. You are better off making your own henna and designs.
