What is a "thread net?"
 

Several of you recommended a thread net when using monofilament thread. I've never heard of this. My machine doesn't like the monofilament threads I have tried it seems but I've only tried a couple of brands. These are the brands my Bernina dealer recommends but if a thread net helps I want to learn about that. Thanks!

A thread net is a nylon net tube that is stretchy, you slip it over your spool of thread, it keeps the thread from * falling* off the spool, keeps it feeding correctly. If you type ( thread net) into google images you can see what they look like

Kind of like the netting people who are cooking food in a restaurant wear only this is made for thread. I have never used one before. I don't use mono-filament thread much anymore but I use the type made by Sulky.

They are the same as the rosebud covers you can get at the florist. I know that JoAnns and Superior Threads carry them at a fairly inexpensive price as well.

Here's what they look like in a package:

and here's what they look like on a spool:

although that particular brand's nets are more coarse than the Superior Threads ones. The latter one I purchased in yardage and cut off pieces to put around my Christmas paper rolls to keep the rolls neat when I store them in a tall basket. The Superior Threads type thread nets come pre-cut and are very soft. Both work for either task.

The monofilament thread needs to stand upright to come up into the thread uptake guide (or whatever that dohicky is called). On an earlier machine, I put the spool upright into a glass jar so the thread came up correctly.
