Resources - Pad Patterns
If you want to make your own pads, there are lots of resources online. Youtube videos and patterns free to community groups and for self use. If you make pads to sell, please buy the pattern rights as well as inform the designers that you are using their patterns.
I only want to give you a fast start into your searches. I always find more amazing things when I look.
Here I will insert links to pad patterns.
A good start is to google Luna Wolf patterns.
