The roller foot easily sews over materials with uneven surfaces, such as leather, velvet, and floral fabrics. Choose stitches with forward-oriented stitch patterns from your sewing machine, and if necessary, place a Dissolve-A-Way stabilizer from Husqvarna VIKING underneath for a beautiful stitch appearance. Your stitch won't become unrecognizable in the fabric; the stabilizer keeps your stitch nicely on the fabric surface. For machine groups 1-9.
