Needles
Along with thread, needles are very important to stitch formation. Many
“mechanical” problems and damage to fabrics can be traced to a bent,
damaged, or incorrect size or type needle. Approximately 60% of all
needles made are discarded at some stage of production. When selecting the correct needle for any serging project, three things must be
considered:
Needle system – 130/705H
Needle point – to assure stitch formation and avoid fabric damage
Needle size – smaller for lightweight fabrics; larger for heavier ones
If the needle is:
Too small – the thread can’t stay in the groove to form a loop
to be picked up by the looper
Bent – thread loop forms too far away from looper, which can’t
enter loop to form stitch
Blunt – needle won’t pierce fabric so no thread loop forms to make
a stitch
Need To Know
Mastering
Your
BERNINA
Notes
®
• Never use a needle bigger than size 90/14 in your serger; larger
needles can interfere with looper movement and cause damage.
• Needle should be changed every 4-6 hours of sewing. The needle
is the most inexpensive part in your serger but is one of the most
crucial for getting good results and keeping your machine running
well. Don’t let false economy keep you from doing what is best for
your sewing projects and your machine.
• European needles are chrome-plated to glide through fabric easily.
• The selected thread should fit in the groove on the front of the
needle. If it isn’t protected by the groove, a needle with a larger
groove should be used.
• Always make sure needles are fully inserted as high as possible,
with the flat side to the back.
Needle Size Conversion
European vs. Domestic
60 = 8
70 = 10
75 = 11
80 = 12
90 = 14
100 = 16
110 = 18
120 = 19
Regardless of the system, the greater
the number, the larger the diameter
of the needle. Never use a needle
larger than size 90/14 in your serger!

Thread
Poor quality or the wrong type of thread can cause poor stitches on any
machine. Thread passes through the eye of the needle approximately
37 times in a “see-saw” action before it forms a single stitch. Poor
quality thread results in crooked and looped stitches, puckered seams,
frayed thread, and/or needle breakage. To achieve quality stitches, an
overlock machine needs three things: correct thread, correct size
needle, and properly adjusted settings.
Several factors such as the fiber, twist, ply, finish, and size of thread
must be considered for use with today’s fabrics for fine stitches.
Staple – refers to the length of fibers used to twist together to form a
single ply. Domestic thread fiber lengths are usually 1½” to 2½” long
while European threads use 5½” to 6½” lengths.
Mastering
Your
BERNINA
Notes
®
Ply – number of strands twisted together to make a single thread.
Roll – the tendency of thread to roll to the right or left during
stitching, causing the stitch to appear slightly crooked. Poor quality
threads are more likely to roll.
Twist – the crimping of fibers which causes them to interlock firmly into
a single ply . Thread should not untwist during stitching. This will cause
skipped stitches, thread breakage, crooked stitches, and weak spots in
seams.
Right twist – most American
threads are twisted to the right,
causing some rolling. This gives
average stitch quality.
Left twist – Most commercial and
imported threads are twisted to
the left, giving better than average
stitch quality . Lef t twist resists
rolling and makes a larger loop for
the hook point to enter, reducing
skipped stitches.

Thread
Wearable art embellishment has necessitated the creation and marketing of many new thread types, such as rayons and metallics.
Threads made in West Germany are left twist threads; Mettler and
Isacord threads are also left twist. To test the twist of a thread: while
holding the spool in the left hand, roll the strand of thread towards you
with one thumb. Left twist will tighten, right twist will loosen.
Fiber – refers to the type of material used to produce the thread.
Some commonly used threads:
• Polyester Overlock Thread – such as Mettler Metrocor
Thinner than regular sewing thread, eliminating bulk in serger
stitch formations. An excellent all-purpose serger thread.
• Texturized Nylon Thread – such as YLI Woolly Nylon
and Mettler Metroflock. A very elastic thread with excellent
coverage; perfect for rolled edges and knit seams. Available
in solid and variegated colors, and metallics.
• Polyester Topstitching Thread – such as YLI Jeans Stitch
& Mettler Cordonnet – this heavy thread is used for decorative
stitching, such as flatlocked seams and overcast edges. Also
nice for cover and chain stitching. Available in solid and
variegated colors.
• Rayon Decorative Threads – such as YLI Pearl Crown Rayon
& YLI Designer 6 – shiny threads for decorative applications.
Pearl Crown Rayon is twisted, while Designer 6 is untwisted.
Available in solid and variegated colors.
• Metallic Decorative Threads – such as YLI Candlelight –
adds a bit of glitz to seams and edgings.
• Decorative Sewing Threads – sewing machine threads can
also be used in the serger, and are particularly effective when
several are used together as one thread.

Storage of Thread
Thread does wear out and should be stored with care to keep it usable
as long as possible. Extreme moisture may cause thread to swell while
very dry conditions can leave it dry and brittle as it ages. Store thread
in a covered container (thread box with a lid, cabinet with doors, or
drawers that close) if possible to keep it dust-free.
Be wary of old spools of thread recovered from Grandma’s sewing
box. The fibers may be so weak and brittle that even if it sews into a
seam, it may be so unstable that the garment or project will not hold
together and the life of the project may be considerably shortened.

Take 2-3 stitches on the fabric. Lower the needles into the fabric.
Raise the presser foot and with your left hand gently pull the thread chain
around the needles to the knife.
Lower the presser foot and continue serging (cutting off the excess
thread chain) until you are one stitch off the end of the fabric.
Locate the Stitch Selection lever on the right side of the cloth plate; pull
it towards you, releasing the thread chain from the stitch tongue.
Raise the presser foot and carefully flip the fabric over so that the
lower looper side of the previously serged seam will be overstitched.
Place the fabric under the presser foot so that the first stitch will
enter the fabric when you begin stitching.
Slide the Stitch Selection lever towards the body of the serger.
Serge for about 1”, overstitching the previous stitching. Guide the fabric
so as not to cut the previous stitching. Option: Rotate upper knife up.
Raise the toe of the presser foot and rotate the fabric 90° clockwise.
Serge off the edge of the fabric.
If the upper knife is up, rotate it down into the cutting position.

Locate the seam guide markings on the knife guard. Measurements
shown are distances from the right needle. When using the left needle,
add 1/8” to measurements.
Tip: Use a permanent marker to highlight the raised markings; this is
particularly useful for those with “mature” eyesight.
Fold fabric in half to 2½” x 6”.
Align the fold of the fabric with the ½” mark on the knife guard (the left
needle is being used). Serge the seam, cutting off exactly 3/8”.

Adjust stitch length to 4mm.
Increase the presser foot pressure.
Locate and raise the roller guide in the front of the presser foot. Turn the
handwheel to lower the needles. (This also lowers the feed dog.) Raise
the presser foot and insert the elastic through the slot and under the
presser foot until it touches the needles.
Lower the presser foot and serge a few stitches to catch and straighten
the elastic along the right edge of the slot. Turn the handwheel to lower
the needles.
Lower the roller guide. Using the small screwdriver, adjust the guide
plate on the presser foot to the width of the elastic.
Locate the pressure adjustment set screw (on the top of the roller guide)
and turn the screw counterclockwise to completely loosen the pressure
on the roller .
Place the fabric under the presser foot and begin serging. Slowly tighten
the pressure adjustment set screw to increase the pressure on the roller
and stretch the elastic. Note: Do not over tighten the screw. Excessive
pressure on the elastic will bind the fabric. Serge the elastic onto the

thread tail.
Mastering
Your
BERNINA
Notes
®
Continue serging around the square, crossing over previous stitching.
Use a seam sealant on the untrimmed thread tails (or use a tapestry
needle to weave the thread tail back through the stitching). When the
seam sealant is dry, trim the thread tails.
OPTION II
Before serging, trim away the seam allowance (¼”) for about 2” on each
corner of the square.
Beginning at one trimmed corner, serge (cutting ¼” as you sew) to the
end of the fabric. Take one stitch off the end of the fabric.
Locate the rolled hem lever on the stitch plate and pull the white lever
towards you. This will free the thread from the stitch finger.
Lift the presser foot and carefully pivot the fabric 90° clockwise.
Return the rolled hem lever to normal (away from you).
Place the needle one stitch into the fabric and lower the presser foot.
Continue serging until you are one stitch off the next corner.
Repeat the turning procedure and continue serging.
Trim and mount the samples.
