SINGER 414 - Manual (Page 7)

The selection of thread should be based on the fabric to be stitched. The thread should
♦ blend with the fabric in colour, fibre and size.
NEEDLE AND THREAD SELECTION
Silk and wool fabrics should be stitched with silk thread; cotton fabrics should be
stitched with cotton or cotton mercerised thread, etc. The thread must be of a size that
will imbed itself into the texture of the fabric. Thread that is too heavy for the fabric
will remain on the surface and become weakened by friction and abrasion when worn.
The selection of the needle should be based on both the fabric and thread being used.
The eye of the needle must be large enough for the thread to pass freely through it. The
blade of the needle must be fine enough not to mar the fabric with too large a puncture,
yet heavy enough to pierce the fabric without binding or deflecting.
You will obtain best stitching results from your Sewing Machine if it is fitted, with a
SINGER" Needle.
