SINGER 611 - Manual (Page 7)

NEEDLE AND THREAD SELECTION
The selection of thread should be based on the fabric to be stitched,
the fabric in colour, fibre and size.
The thread should blend with
Silk and wool fabrics should be stitched with silk thread; cotton fabrics $br)uld be stitcied 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 fric­
tion and abrasion.
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 Sewhng Machine if it is fitted wuth a SINGER* Needle.
