Stitches You Can Serger on the Elna 745

• SAFETY 4 THREAD
  A 3-thread overlock stitch that adds a second
  needle thread. The stitch stretches without
  breaking. The second needle thread
  reinforces the durability and strength of the
  stitch, but the stitch retains its elasticity
• STRETCH KNIT
  The same characteristics as the Safety 4
  Thread. The Stretch Knit program uses the
  differential feed and stitch length settings to
  prevent knitwear from stretching while sewing
• 5 THREAD
  A true 5 thread industrial stitch consists of two
  stitches sewn simultaneously. 2 threads form
  the chainstitch and 3 threads form the
  overlock. It is found on medium to
  heavyweight woven fabrics.
• 3 THREAD WIDE
  Three threads lock together on the fabric edge
  forming a balanced stitch. The overlock stitch
  is suitable for medium to heavyweight fabrics.
• OVERLOCK 3
  The same characteristics as the 3 Thread
  Wide. This narrower version is suitable for
  light to medium weight fabrics.
  Common Uses
  • Construction method for lingerie.
  • Edge finish on single layer of fabric.
• FLATLOCK 3
  Three threads form an unbalanced stitch that
  can be pulled open into a flat seam. The seam
  resembles the exposed stitch seen on ready-
  to-wear sweatshirts and knit sportswear.
  Common Uses
  • Construction method for bulky knitwear.
  • Decorative accent.
• BLANKET
  An edge finish that uses decorative thread in
  the needle. The upper and lower looper
  threads pull the needle thread so it is visible
  on both the top and underside of the fabric.
  Common Uses
  • Edge finish for a single layer of fabric like
  a blanket or felted scarf.
  • Decorative accent.
• FLATLOCK 2
  The needle and lower looper threads form a
  stitch that can be pulled flat.
  Common Uses
  • Construction method for undergarments.
  • Hemming technique.
• OVERCAST 2
  The needle and lower looper threads form an
  edge finish that is lightweight and flat.
  Common Uses
  • Finish an open seam edge on lightweight
  fabrics.
• NARROW HEM 3
  Three threads form a balanced stitch that is a
  great narrow edge finish.
  Common Uses
  • Hemming method for scarves, napkins
  and ruffles.
  • Construction method for undergarments
  made of lightweight knit fabrics
• ROLLED HEM 2
  The needle and lower looper threads form a
  stitch that rolls the fabric before encasing the
  edge.
  Common Uses
  • Since there are only 2 threads, the result
  is lighter and finer than Rolled Hem 3.
  This is an advantage for lightweight
  fabrics like chiffon and bridal veiling
  edging.
• STRETCH WRAPPED
  A stretch stitch that uses two needles and the
  lower looper. This is the stitch that has the
  maximum stretch; the second needle thread
  increases the stitch’s durability.
  Common Uses
  • Construction method for exercise and
  swimwear.
• TRIPLE COVER HEM
  The Triple Cover Hem measures 5.0 mm in
  width. It uses three needles and the chain
  looper to form 3 lines of what looks like
  parallel straight stitches.
  Common Uses
  • Hem finish.
  • Topstitching.
  • Belt loops
• COVER HEM WIDE
  A version of the cover hem that measures 5.0
  mm in width. The garment industry commonly
  uses this wider width on knitwear.
  Common Uses
  • Hem finish.
  • Topstitching.
  • Belt loops
• COVER HEM NARROW
  The cover hem measures 2.5 mm in width. It
  uses two needles and the chain looper to form
  what look like parallel straight stitches.
  Common Uses
  • Hem finish on knit fabrics.
  • Topstitching.
  • Pintucks.
• CHAINSTITCH
  A 2 thread chainstitch or double chainstitch
  uses one needle and the chain looper to form
  a straight stitch. The chainstitch is a stable
  stitch that has a slight amount of stretch not
  present in the straight stitch sewn by a
  conventional sewing machine.
  Common Uses
  • Construction method on woven fabrics to
  create an open seam allowance.
  • Sew knitwear together where the seam
  needs to be stable.
  • Sew on bias tape
