At that point, I think it would be more a decorative, embroidery type stitch than quilting. Assuming PaperPrincess is right about the weight (I have no idea), I know I would not be able to run it through my Bernina 350. I could run that thread through my old Singer Genie 353. Check your manual & then maybe make a practice sandwich to see whether you even like the look. One other thing I can share from my experience working with jeans thread (and then, of course, you need a size 14/90 machine needle), is that it shed lint like crazy. I was just doing a simple hemming project & had to clean out my bobbin twice just while doing 2 pant legs. Sometimes we save ourselves a few bucks with thread & then end up paying $200 to get our machine serviced.
