Thread question Singer 111G156 older recomendation

[bnsmith]

Just getting into this hobby

I see from an older manual the recommended thread to use

 

How does this match to from the Toledo site

 

Is the "Cotton Thread" measurement not used any more?   Do we worry about twist as well?

 

Thanks Brian

I know there is some thread companies that list & sale left hand twist sewing thread. 

Heck maybe it is all left hand twist.

Here is a quick cross reference showing some of the various thread size standards from a reputable North American thread manufacturer ( A&E ).

My thoughts:

I think the Cotton thread referenced in the manual was for Thread Weight not Cotton Thread Count. The Thread Weight basically came from a Japanese standard called the Gunze Count Standard which the US adopted but all weights are not equal. A 50wt with 2 strands (50/2) is lighter weight-wise then 50/3 but both would be labelled as 50wt.

Thread and it's standards is a very deep dark rabbit hole. Depending a lot on which country or continent you are located. In North America the general rule is the US "V" size or the "Tex" size while Europe uses the metric system and their thread would be shown as "Tkt" or "M" or just a number. Then you have Canada where you have a real mix of metric, Imperial and US measurements depending on what country the item is being supplied from. Often thread is labeled in both metric and US standards.

I use the "V" system which is based on size rather then the "Tex" as "Tex" is based on how much 1000 meters of thread weights in grams. If a machine can handle a #22 (140 metric) needle I know it can handle V138 (M20) thread in thin material or V92 (M30) in thicker material.
