The first seven cones of Superior Threads So Fine #50 were purchased from my LQS, Eddie's Quilting Bee. That was very convenient but since I'm starting a business I set up a wholesale account with Superior Threads. They're such nice people and oh so helpful. Aren't they pretty colors? Between all of these cones they'll blend with the majority of fabrics. You'd be surprised how much those bright lime and orange colors just blend into the background of busy pieced quilts. So far I love how strong the So Fine thread is while stitching away with Freddie. It doesn't shred at all and doesn't make too much lint as compared to cotton threads. I also got a few trial spools of Fantastico, a variegated thread, to see how I like it. Finally someone told me that Floriani's machine embroidery thread also worked well in longarm quilting machines. I found a few spools on sale for $4/each to try them out as well. Oh no, watch out, there may soon be a thread stash.
