Singer double needle thread snagging and skipped stitch on one side

[Constabulary]

I have a 212 (112 predecessor) and I never use left twist thread (IMO that only is necessary for decorative reasons on visible seams - if wanted) and I would not recommend any bonded thread at all. I mainly sew heavy canvas. Polyester or Poly-Cotton thread is what IMO works best. Look for Aman SERAFIL for leather or for Jeans look for Aman RASANT or SABA ( I prefer RASANT). Look for fine burs or worn in groves in your thread path and the hook and polish them. Also check the needle hook distance and needle height. The needle could be a tad to high.

@Constabulary thanks for the advice.  I will check all those options.  I really appreciate the jeans thread brand suggestions.

No more rolls of thread from Canada regardless of the low price.

@DMH you may want to consider thread from Coats their Tristar line. From their website ( https://www.coats.com/en/products/threads/tristar/tristar/ ) they say :

Tristar cuts cleanly without separation of the plies at thread trimming. Its low friction finish reduces the effects of needle heat and abrasion. It is perfect for multi-directional sewing and it also eliminates the need for right-twist thread for twin needle lockstitch applications, simplifying thread ordering and inventory.

As a note:

Kava as a house brand for Quebec produced in Canada by Kava Inc. also known as Cansew Inc., a Montreal-based company with its own factory and dyeing facilities at 7609 St. Hubert St., Montreal, Quebec.

I haven't used thread from the Cansew or Kava manufacturer, that I can remember, but have been very satisfied with the results of American & Efird bonded nylon threads. As I am starting to run low on V92 and V138 I am planning on giving the Coats Nylbond and the Cansew bonded nylon thread CB138 a try in the near future.

I just recently switched off of A&E , and got a couple cases of Coats nylon t-70, and ( for me ) I finding it better Bond/stronger, and you get less of the little annoying snaggy spots on the thread windings as you work threw the Cones .
The lb. Cone snaggy spots I was getting on the A&E might have just been just on that specific Thread run ? . but overall I like the Coats much better.

That is good information.
