Practical Stitches - Applications
Sewing Knit Fabrics
Start With a New Needle
•
blunt needles can damage knits
Use a Stretch Needle (130/705 H-S) if
Necessary
•
the needle point slides easily between the
fibers
Use a Fine Sewing Thread
•
coarse threads can damage knits and
cause holes when the garment is washed
When Basting, Use a Darning Thread
•
very lightweight (80 weight) darning
thread is easier to remove once the seam
is complete
Sew a Test if Necessary
•
the elasticity of today’s knit fabrics varies
greatly
•
adjust basic settings to suit the fabric, the
seam should be as elastic as the fabric
•
for greater elasticity use a shorter stitch
length and/or stitch width (only one of
these adjustments may be necessary)
Presser Foot Pressure
•
soft, loose knits can wave when sewn:
•
reduce the pressure until the seam lies
flat
•
the sewing computer must still feed the
fabric properly
Possible Problems With Sewing Knits
Seam Becomes Wavy
•
oversew a thread along the edge
•
after sewing adjust edges by pulling the
thread to regain the original length of the
fabric and press seam flat
Edges Roll
•
do not sew right on the edge but about
5mm in from the edge
•
cut off allowance after finished sewing
Seams Which Pull or Stretch
•
reinforce seams with a ribbon (e.g.
shoulder ribbon) before sewing
•
different stretch ribbons are available.
These can be sewn to give more security
to the seam
