How can I make perfect sticky rice?
I am happy to give you a brief idea, but you may have to tell me how much info you need


Get the lotus leaves from chinese shop and they are usually dried leaves, so you need to soak them in water for a night.  After that give it a wash and cut it to the right side
sticky rice is a type of rice, so that's what you need. Don't use any other rice as they won't stick. You will need to soak the rice in water for couple of hours and add couple drops of oil. 
Prepare whatever you want to put in your rice like mushroom and meat
When u make the wrap, put a layer of rice on the leaf and then place the meat and mushroom on the rice.  After that put another layer of rice on top and wrap it up
Put the wrapped rice to steam and I cannot help you with the time, but it's between 10-20 mins


Good luck
