I first used the nylon thread then read that the polyester is softer so I switched to that. It is much nicer on my quilts! I did decrease the tension a bit but found a solution to all of the problems. If you have a stand-up spool holder like you would use for metallic thread, use that or if you have an extra spool stand like I do, use it! Clear threads do better if they come off the TOP! I just read that & put my stand on, left the tension alone & sewed like crazy. NO PROBLEMS!!!! YAY! Try it, you'll like it! :lol:
