When I saw your dolls I thought: I like it that they don't have faces. Native Americans never put faces on the dolls they made (make) for their children. That way they child can use their imagineation to give the doll the personality they want. Nothing is worse than to see a doll with a smiling face when they are feeling sad or even angry. Please consider making some dolls without faces for these children. As for the skirts, you could just do a simple continual nine patch pattern.
