The KGD pads are really easy to work with.
You can peel the very thin outside layers off, you'll notice those two layers are not as fluffy. Depending on what you're wicking you can peel off one layer, both layers, or leave the outside layers intact. I tend to leave one layer on with smaller
coils and no outside layers for larger
coils. The surface layer is thin, but dense, so you can use it to your advantage in some situations.
Besides the layers you want to make sure all the fibers run in the same direction and the section is even/smooth. You don't really need to shape it or roll it. Just roll the tip tight to get
through the coil. Make sure when you pull the cotton through you feel some resistance, but not loose fitting. It's good put tension on both tails as you pull it through the coil. Don't oversature and it's perfect.
