Algorithmic Quilting Pattern Generation for Pieced Quilts

Free-motion quilting patterns are functional and decorative patterns sewn on pieced quilts using a single-line continuous stitch path for each region of the quilt. Seven families of quilting patterns are commonly used by quilters [3]. We present an approach for computationally generating three of these families. The user can control the design for each family based on a set of parameters, including the density and general layout of the pattern as well as the decorative elements. Our algorithm starts by sampling a point set in a designated region, generates a skeleton path over that set, then inserts decorative elements along the skeleton. We provide digital and quilted examples for each type of pattern.
