I use the YLI brand. I set it in a small jar with poster putty in the bottom to keep it from moving. I cut a small hole in the jar lid put half a drinking straw in there and threaded it through. This gets the twists and loops out before it gets to the tension discs. I run it through a thread stand after it leaves the jar and before it gets to the guides on my machine. I have several machines, singer, janome, whiite, this works on all of them. I use regular thread in the bobbin. I have had no trouble with this method. Hope this helps someone. :-)
