My machine breaks thread

[Bobbielinks]

It's not catching on anything and it's not threaded improperly. That I know of for certain. I had problems for 2 1/2 years with the thread breaking and finally bought a cone of 50 wt. and no more problems. I guess I should talk to my dealer. I like to do machine applique and I use different colors and small spools, so I have to get it figured out. To make the tension less tight, do I go up in numbers or down in numbers? Sorry, I'm not wise to this part.

Righty tighty, lefty loosey

I use a topstitch needle for all sewing and quilting. I rarely have a thread problem as long as I use the right size needle for the thread weight. Also be sure the spool of thread is wound to be used vertically or horizontal. Most are for vertical. Manufacturers went to horizontal spool pins because it's cheaper, not better.

I have been sewing for decades and I still have a little chart to check when I have thread problems. I printed out the little stick man chart from Superior Thread and keep it by my machine. I also made myself a little cardboard chart that says ....to reduce upper thread tension dial the number smaller...to increase upper thread tension dial the number bigger. Below that I printed for bobbin adjustments turn the tiny screw ....tighty-righty or lefty-loosey I keep it in the drawer of my accessories box that came with my Bernina.
