Any serger thread I've seen for sale is much thinner than 50 wt. Presencia sells 50wt. cotton thread on spools. If you are having issues with your Bernina 830 I would suspect it's because you're using serger thread. The new 830E's are very fussy about using quality thread. If you're feeding serger thread through it, I question why your dealer would tell you that.

People may be misunderstanding that a cone of thread is serger thread. It is not. There are many, quality brands of thread on cones that are not serger threads. This is a thin, serger thread, 100% polyester http://sewtrue.com/Store/Maxi-Lock-S...EACH-P184.html

Superior threads has a free (for now) CD that will teach you the different applications for the different types of thread on the market.


Superior threads say, "Serger Thread
Because sergers (overlock machines) simultaneously use multiple cones of thread, there are many cheap serger threads on the market. The cones of serger thread available at discount chain stores are an inexpensive spun poly. These are OK when used for serging but not recommended for other applications. Multi-filament polyester thread such as So Fine! #50 makes a clean, lint-free serger thread but is more expensive than spun poly. Omni Thread is a poly-wrapped poly core thread ideal for serging."

I have done it lots of times. If its older thread , do the break test before using to make sure its still strong. If you have any questions about its strenght... check a regular spool of thread ( new or newer) see if still is compartively strong.
Most serger thread is 2 ply and most regular thread is 3 ply....

Serger thread is made with short staple, not long or extra long staple. Thread is one thing Ive never skimped on. I feel with the price of fabric and my effort, i dont want the project to go south over time because of the wrong thread. I do buy serger thread but only for serger. Here is info about difference in threads.

Can you use serger thread to applique? I have cones of what people say is serger thread which came free with sewing machines. I want to do some applique and the colours are just correct for these pieces. I will be using sticky of some form to hold pieces down before sewing edges.

Spun poly thread is the cheapest thread you can buy.

Cone thread is not necessarily serger thread. MANY great, quilting thread comes on cones. If it's the spun polyester junk that is really serger thread...there are better options. There are so many delicious threads out there!
