They've had their polyester threads for years as I haven't ordered any in probably 4-5 years now. Sorry to hear they're discontinuing it as my machine loves it as well as their cotton threads. They do have a tendency to discontinue certain colors only to bring them back later under a different name and/or code number. I've made a comparison chart for that reason so if and when I need to order more thread, I can go to my chart and see if the new color is actually an old one with a new name. Luckily I have a large stash of thread so haven't had to order any for quite some time. I tend to order 5-10 spools of the colors I use the most so I never run out.
