Stitch Lengths
Stitch Length is determined by the purpose.
A medium stitch length is most common.
Basting stitches are very long.
Reinforcement stitches are very short.Slide3
Standard Stitching
Use
: Permanent seams & construction details.
Most Fabrics
: 10-12 inches
Finer Fabrics
:
Shorter stitch between 12-15 stitches per inch.
Heavy Fabrics
: Longer stitch 8-10 stitches per inch.Slide4
Basting
Machine basting holds two pieces of fabric together until they are permanently stitched.
Used also on a single layer of fabric for:
Easing
Gathering
Marking guidelines
Slide5
Reinforcement Stitching
Adds strength to areas that will be clipped or trimmed close to the stitching line or areas such as armhole, crotch and corners.
Short stitch – 15-20 stitches per inch.Slide6
Stay-stitching
Prevents fabric stretching
Placed along bias & curved edges
Added after
:
Fabric marking
Before pinning
Basting
Permanent stitchingSlide7
Stay-Stitching cont.
Stay-stitching should be done on a single layer of fabric 1/8 inch from seam line & within the seam allowance.
Acts as a guide for clipping & joining curved edges.Slide8
Directional Stitching
Helps prevent a seam from changing or stretching while stitching.
Produced by stitching with or in the direction of the fabric grain.Slide9
Standard Seam
S
titching
Produces
5/8 inch seam
Used in most patterns.
Plain seam: 5/8 inchSlide10
Backstitching
Secures the ends of a row of stitching.
Secures the ends of a row of stitching.
Begin ½ inch in from end.
Stitch backward to edge of fabric.
Continue sewing to other end.
Backstitch ½ inch from end.Slide11
Understitching
& Facings
Understitching
is a row of stitching you sew close to the seam line through the facing and the seam allowances.
Facings
cover the raw edges in a garment such as the armholes, neckline, or other garment opening.Slide12
Understitching
Keeps
facing or the under side of fabric rolled out of sight.
Created from standard
stitching
Stitch from right side of fabric through facing & seam allowances, 1/8 inch from seam line.Slide13
Topstitching
Decorative or functional stitching placed on the outside of a garment.
Outlines – Seams
Secures - Facings
Attaches – Pockets
Stitches - Pleats
Holds - HemsSlide14
Edgestitching
Holds fabric & seams in place.
Row of stitching ¼ inch from finished edge.
Used in areas as:
Neck edges
ZippersSlide15
Stitch-in-the-ditch
Holds
two
or more layers of fabric together at the seams.
Secures
:
Necklines
Armholes
Waistband facings
Standard stitching on the outside of a
garment
in the groove of a seam line.Slide16
Zigzag Stitching
Zigzag stitch uses:
Finish seams
Stitch buttonholes
Attach cording
& elastic
Create decorative designs.
Button Hole
Seam FinishSlide17
Specialty Stitches
