General Construction Seaming

• Use a 4-thread Overlock stitch for most fabrics

• Adjust presser foot pressure for very thick or thin fabrics – Owner's manual pg.____

Serging Knits

• Use Ballpoint or Stretch needles to prevent damage to the fabric.
• Woolly Nylon in the loopers adds to the stretch of the serger stitch.
• Adjust stitch length to 3mm for most seam applications.
• To prevent fabric stretching during sewing
