NEEDLE, THREAD AND FABRIC CHART
4
The needle and thread you choose depends upon the fabric you are stitching.
The correct needle size is important to avoid damaging the fibers of light weight
or tightly woven fabrics, and to prevent needle breakage when stitching heavy
or stiff fabrics.

*
Always use same type and size of thread in both needle and bobbin.
*
Always use a sharp needle.
A blunt point can cause skipped stitches or snag
the fabric. Chemical finishes and man-made fibers blunt the needle faster.
*
Never use a bent needle.
*
If your machine is skipping stitches, replace the needle before looking for
trouble elsewhere.
*
When sewing very fine fabrics, use tissue paper underlay to prevent yarn distor
tion.
* When sewing stretch, very fine fabrics and synthetics, use a BLUE TIPPED
needle. The blue tipped needle effectively prevents skipped stitches.
