I have a HQ Sweet 16 and I also use Connecting Threads thread. Like others above said - it is pretty linty, but I have never had a problem with it on my Sweet 16 or in my Dreamweaver machine. I probably have every color they ever made, bought most of the sets they sell and about 15 of the large cones in various colors. I just clean my machines more often, which is never a bad thing.
