The price reflects time expended and craftsmanship not based purely on size. Larger balls with similar intricacy in detail will reflect in price accordingly. I hand roll yarn to form the ball then, wrap the yarn tightly with serge thread to form a firmer rounder ball. I do not use styrofoam, so they are not perfectly symmetrical. I prefer the feel of the balls made purely of yarn, they are more dense and satisfying to the touch. These are handmade an irregularities are to be expected. Therein, I find beauty.
