Jelly Rolls are collections of color-coordinated fabric strips that resemble the delicious rolled pastry of the same name. Moda Jelly Rolls typically include 40 2.5" wide strips from a single fabric collection. The strips are cut across the width of the fabric, so they are 42" to 45" long including the selvage. Other manufacturers call their pre-cut fabric strips "Roll Ups," "Rolie Polies," "Pixie Strips," or "Bali Pops," but they all mean the same thing to quilters: variety and convenience!
