With my current interest in sewing clothes for American Girl dolls, I've seen my collection of patterns grow by leaps and bounds. In order to reign in the chaos of over 120 plus PDF patterns I have resorted to using 2 inch binders filled with clear plastic sheets . Each binder holds 18 - 20 patterns. With so many patterns it was necessary for me to sort them by categories: Tops, bottoms, dresses etc. Each plastic sleeve is home to the printed out PDF Pattern instructions and the the cut out pattern pieces which I printed on card stock and laminated. I trace the pattern piece onto the fabric with a fabric pen. Secure the traced outline with 2 - 3 pins and cut away.
