Preparation Considerations Before executing decorative stitches, ensure the machine is threaded correctly with polyester or all-purpose thread (weight 50) for durability. Fabric selection plays a critical role: lightweight fabrics (e.g., silk, chiffon) require stabilization (e.g., tear-away or wash-away stabilizer), while medium-weight fabrics (e.g., cotton, linen) can be stitched directly. For cording, use elastic thread (e.g., Gütermann 120) or metallic thread (e.g., Mettler 140) for dimensional effects. Scallop Stitch (Stitch 8) Thread Combination: Pair black or dark gray thread (bottom) with cream or pastel thread (top) for contrast, or use two-toned thread (e.g., silver/gray) for a modern look. Fabric Pairings: Lightweight: Silk dupioni, chiffon (use stabilizer). Medium-weight: Cotton poplin, linen. Steps: 1. Set stitch length to 2.5–3 mm for even scallops. 2. Secure fabric with basting stitches along edges to prevent shifting. 3. Stitch 0.5 cm (3/16") from edge, adjusting width to 5 mm for subtle scallops or 7 mm for pronounced waves. 4. For layered effects, stitch two rows with contrasting threads. Cording Technique (Using Stitch 1 or 4) Thread Combination: Combine elastic thread (top) with regular thread (bottom) for stretch, or use two metallic threads (e.g., gold/silver) for a luxe finish. Fabric Pairings: Structured: Denim, canvas, or upholstery fabric. Soft: Jersey knit or Ponte knit (use a walking foot). Steps: 1. Thread the machine with elastic thread in the top spool and regular thread in the bobbin. 2. Set stitch length to 4–5 mm and width to 0 mm (straight stitch). 3. Stitch parallel lines 0.3 cm (1/8") apart, then pull gently to create a raised cord effect. 4. For knit fabrics, use a zigzag stitch (Stitch 4, width 3 mm) to encase the cord. Satin Stitch Outlines (Stitch 1 with Adjustments) Thread Combination: Use high-luster polyester thread (e.g., Mettler 200) in a single color or two complementary shades (e.g., navy/white) for depth. Fabric Pairings: Smooth: Cotton sateen, silk, or rayon. Textured: Linen or burlap (pre-wash to prevent fraying). Steps: 1. Lower the presser foot pressure slightly for delicate fabrics. 2. Set stitch length to 1.5–2 mm and width to 0 mm. 3. Stitch along marked outlines (e.g., floral motifs, geometric shapes) with consistent tension. 4. For double satin stitch, repeat the outline with a contrasting thread slightly offset.
