So you know how to make the mehndi, roll and fill the cones, now what? If you haven’t had any formal mehndi training (many artist are self taught including me) then the next step is to just practice, look at all the patterns and shapes and fills and start trying to emulate them. Start practising on paper with a pen or pencil until you feel you are ready to take it to the next level with real mehndi.
I found a really useful way to store my favourite mehndi designs until I was ready to do them on a real hand. Draw around your hand on some card and then with real mehndi (no oils added just a water and henna mixture) draw your favourite designs, leave it overnight to dry and then laminate it. This will seal in the design without the mess you get when the mehndi starts to dry and crumble off.
