I had trouble using invisible thread, especially Superior's, until I worked on my setup for feeding the thread. Superior was a bigger problem originally because they put the thread on really heavy spools so you can't use them on the regular spindle because the weight of the spool would cause the thread to stretch. So, I moved the thread off of the machine and feed it from the top. I had to do this with Superior's thread, but it works well with other invisible threads, too, whether polyester or nylon. I put a thread net around the spool or cone to keep the thread from sliding off and getting tangled. Then I run the thread through 2 packing peanuts, separated by the guide on my spool holder. The peanuts keep the thread from kinking up and getting hung up. With this setup, I've been able to quilt with invisible thread with absolutely no problems. Here's a picture of my setup:
Of course, you also need to adjust your tension which usually needs to be looser.
