Appliqué is the technique of attaching other fabrics to the final wearable piece. For tackle twill, fabric is cut, layered and positioned with an adhesive backing and attached by means of a zigzag stitch. Since large areas of color are constructed with layered fabrics, fewer stitches are needed to attach the final design. This combination of fabrics and lower stitching translates to a lower cost as well. Keep in mind that the more intricate the design and more material-colors involved, cost will increase.
