Good for you - try it on a tiny corner of your intended fabric first, to see how long you need to leave it on - in my case it was only seconds. I tried to do all four at once, and by the time I had done the fourth, the first was unusable because it had spread too much.
Also, some batiks work better than others, so if your first choice doesn't produce nice results, don't give up, try another one. Best of luck.
