Standard Sewing Machine
Used For:
• Regular stitching
• Machine basting
• Reinforcement stitching
Serger
A Specialized type of sewing machine that can
•
stitch, trim, and finish all in one
simple step.
• Sometimes called “Overlockers”
Embroidery Machine
Used for:
• Monogramming
• Personalizing
• Special Designs
Problems and Solutions
• Skipped stitches- needle comes unthreaded, be sure to
take up lever is at the highest point when beginning to stitch
thread knots up on the underside of fabric, hold thread ends
under and to the back of the presser foot
• Stitch length – When joining 2 heavy fabrics. Keeps them
from joining unevenly.
• Tension- Check tension of upper thread if the topstitch seams
loose.
• Special fabrics – Different fabrics require different types
of presser foots, Thread, and a change of settings on the sewing machine.
Parts and their uses
• Needles- Hold the upper thread on the sewing machine, comes in many
types and sizes, you must always replace when it becomes dull, bent, or rough.
• Presser Feet- holds fabric against the feed dogs which moves the
fabric forward.
• Feed regulator- Feeds fabric thru the machine while stitching.
Changes direction when the reverse stitch button is pressed.
Stitches
• Types – Three-thread serger, four- thread, two-thread, two-thread
stitch, five-thread, rolled hemstitch, flatlock, and cover stitch.
• Sizes and length-
Basting is temporary stitching. Large
stitches that can be removed. May be done by hand or with a long stitch
length on sewing machine.
– Reinforced stitching is typically seen in crotches of pants. Use stitch length 1 on
sewing machine for reinforced stitching.
– Standard stitching is used most often. Stitch length 2/3 can be used.
• Tension -
the heavier the thread, the looser the tension should be
balance stitch, adjust the tension whenever you change
fabrics
Special Situations
• Corners - Trim edges to reduce bulk.
When you push out corner it should be to a
point.
• Curves – Make sure seam allowance is the
same even when you have a curve. Reduce
bulk to make seam lie flat.
• The bent handles on these
shears allow fabric to lie flat
on the table as you cut.
• Blades are usually 7 to 8
inches in length.
• Also know as Bent-handled
shears.
• These scissors have small
round handles.
• Blades are 4 to 6 inches in
length (the blades are
different in widths).
• Use the to trim seams, clip
curves, and cut into corners.
• With these shears, you can
finish a seam edge or other raw
edge on firmly woven fabric.
• The zigzag design helps to
prevent raveling.
• 3 to 4 inches in length,
with very pointed blades.
• Use for cutting
buttonholes & Trimming
close to the embroidery
hoop.
• Resembles a pizza cutter.
• Can make straight clean cuts
through multiple layers of
fabric.
• Cutter must be used with a
mat.
•Can remove stitches with
the blades on one end of
this pen-shaped gadget.
• Be careful not to cut the
fabric.
• This tool ha
spring-action
blades for
clipping thread
ends or stitches.
• Are manipulated by
hand along outlines of
the pattern pieces of
the marker.
• They cut multiples
layers of fabric.
• A device that generates
an intense, powerful
beam of light.
• Cut one garment a
piece at a time.
• They’re economical
because they fast and
accurate.
Pressing: Equipment
•Press Cloth- A press cloth is a layer
of fabric placed between
the fabric and the iron to
protect the fabric from
scorching or shining.
•Tailor’s Ham- is convenient for
shaping the fabric when
making dressmaker
suits or coat.
•Sleeve Board- A sleeve board is a
small ironing board that is
narrow enough to fit into a sleeve.
•Seam Roll- A seam roll is a
two-sided cylinder, one side
covered with wool
and the other side
covered with cotton.
•Point Presser- section for pressing
narrow, hard to reach seams of collars; belts;
cuffs; corners; points, etc.
•Pounding Block-
Also known as a tailors clapper.
A clapper/pounding block is used to flatten a
seam, pleat, dart, lapel, buttonhole, etc.
•Needle Board- A board
that holds needles
in a loom.
•Ironing Board- A long, narrow
padded board, often with collapsible
supporting legs,
used as a working
surface for ironing.
• Iron- A metal appliance with a
handle and a weighted
flat bottom, used when
heated to press
wrinkles from fabric.
*Make sure to keep iron clean!
Pressing: Techniques
• Specialized Fabrics- When pressing corduroy or
pile fabrics, like velvet, if you don’t press on the
wrong side of the fabric, the iron’s impression will
be left on the fabric.

• Placing these fabrics right side down on a needle
board will help preserve texture.
Use of Pressing Equipment
• The iron is the most important pressing
tool.
• Avoid pressing over pins, sippers, and
other metal objects that will scratch the
bottom of the iron.
• Most pressing equipment,
like the tailors ham, sleeve
board, point presser, etc.,
serve a certain purpose.
Types of Seams
• Plain seams should be serged and trimmed, or
stitched with a seam allowance of 5/8 of an
inch.
• Perfect for beginner projects from pillows to
pants.
Types of Seams
• A Flat-felled seam is self-enclosed and requires
no additional seam finishing technique.
• Used where durability is needed or a tailored
appearance is desired.
Types of Seams

• A French seam is a durable self enclosed
seam that is used to conceal seam
allowances.

Types of Seams
• The Lapped seam is a strong smooth seam that
should lie perfectly flat. It gets its strength
because its sewn with two rows of stitching.

Clean Finish “aka” Turned and Stitched
• A clean finish is turned
under 1/8 to ¼ of the raw
edge of fabric and then
stitched close to the
folded edge.
• If you want a smooth
edge on the inside of the
garment you would do a
clean finish.
Pinked Finish
Most firmly woven
fabrics can be
trimmed with pinking
shears.
Pinking the fabric
doesn’t completely
prevent raveling.
Pinking shears give
an attractive edge.
• For more
protection, stitch
¼ inch from each
edge before
pinking.
•
Bound
Finish
A bound finish is used
frequently on unlined
coats and jackets. Also
in dresses and other
items that have a
tendency to ravel.
• Appropriate fabrics
are medium/medium
heavy and heavyweight
woven fabrics.
Zigzag Finish

adjusted to
accommodate and
prevent raveling.
This finish is used on
medium- to
heavyweight fabrics.
Piped Finish
• Piping is a narrow
band of fabric
stitched into the
seam to accent the
seam line or outer
edge of a garment.
• Piping can be

fraying and it also
consistently performs
well.
Pearl Crown Rayon Thread
• The fibers used in this
thread are continuous
filament which is
virtually hairless.
• The fibers are twisted
to add to the sheen and
make the thread
stronger and less
prone to fraying and
more durable then
some other heavy
rayons.

• Adds luminous accents
to machine
embroidery.
• Some offer nylon
cores, rice paper

mercerized
cotton for
crafting
decorated
crochet items.

stiffed with
starch.
Textured Nylon Thread

General purpose
threads
Polyester

must take your body measurements.
•After you have figured your figure type the next step is
to find your pattern size. Check your measurements and
line them up with what’s on the chart located at the
back of the patter envelope.
Pinning Patterns
• Pin the grain line first, if you don’t pin the grain line correctly
your finished garment will not hang correctly.
• Pin perpendicular to the bold line.
Pinning Continued

piece.
Marking
