Help me with fabric painting...

Tweet

i recently engaged in making pouches. I want to make them a little bit colorful and unique of course. I want to print some designs on my satin pouches. Please help me how I can make this. I do not want to buy a heat press machine just for small pouches. I am planning to use fabric paint but my problem is where will I find some designs or stencils? I do not know how to draw so I really need some pattern. Please help me...
