The Free-Forming Method

The hair is parted/sectioned off as desired and then left-alone until the next wash. The hair will naturally lock in its sections over time, but with no twisting or interfering on your behalf. After each wash, you will part/section off the new hair growth at the roots so that the locs do not merge together, but then leave everything else alone-to free form.
Pros Cons
This method is free and hassle-free. You hair will be a little wild-looking at the beginning, and for quite a while. But the end results, after years can gorgeous.
