Essential Thread
 

I did a search and couldn't find what I needed to know. I have used Essential thread horizontally in my machine but recently had my bobbin making a rattling noise and the top thread snagging once in awhile. the bobbin wasn't Essential. I finally changed bobbins, filled again with the same thread i'd been using and removed the almost empty Essential spool and put a different brand on. no more rattling.
should Essential threads be used vertically at all? I know there is a rule about the different ways thread is wound. ????????

I've used it both ways and had no problems.

both ways. how about doing FMQ?? I"m about to do that. hopefully.

I've never had a problem either way. I've heard you should always use the same thread in the top and bobbin and that's what I do. I know sometimes you can get by not doing this but I figure why chance it. I like things simple and this helps it be that way.

I HAD A thread do that it was also a getting real low on spool i think that was the problem i then used it for bobbin

matching thread or not
 

It really depends on your machine. My Pfaff doesn't seem to care whether the top and bobbin threads match. However, it DOES care if I don't put the top spool on so the 'dent' doesn't catch thread. Either put it horizontally with the dent on the RIGHTand loosely put the stopper against it - or put it on vertically with the dent on the BOTTOM.

Experiment with different threads. Just make sure that dent isn't catching threads.

According to Superior Threads, you should put all spools on the machine vertically. Sometimes it won't matter, but putting it on horizontally adds an extra twist to the thread as it comes off the spool and that can cause breakage.

Cones should also be vertical on a thread stand according to this, but they unwind from the top.
