SELECTION OF NEEDLES AND THREADS
I
■
The needle ^nd thread you choose depends
upon the fabric you are stitching. The correct
selection of needle and thread is very important
to avoid damaging the fabrics of light weight,
or tightly woven fabrics, and to prevent skip­
ped stitches when sewing on very sheer or
stretchy fabrics or needle breakage when stitch­
ing heavy or stiff fabrics. For best results, sewing
machine needles should be replaced when they
become even slightly dull or bent or at the com­
pletion of every other garment.
A regular needle is suggested for use with
woven fabrics. Needles, style 15 x 1, of the
range in size from 8 to 20 are used on this
machine. The lower number indicates the finer
needle. The most commonly used sizes are 11
and 14.
A ball point needle is recommended for use
with tricots, jerseys, lingeries and power nets.
Unlike sharp pointed needles, which pierce
fibers of knit fabrics destroying elasticity,the
ball point needle slips between fibers without
damage to fabric and skipped stitches.
A wedge point needle is recommended for use
with leather and leather-look vinyls. A wedge
cutting point pierces leather more easily than
ordinary sewing machine needles, resulting in
more satisfactory stitching.
Although it is recommended to use a ball point
needle for knit fabrics, when sewing on very
stretchy fabrics of knits, the placement of a thin
paper below the fabric and the use of a finer
needle are suggested to prevent skip stitches.
Always use the same type and size of thread
in both needle and bobbin. Use good
quality thread without knots for best stitches.
