I use Connecting Threads for piecing.. and sometimes for quilting but I love love love Glide thread for quilting. I use it in my sit down Lizzie. I haven't tried it in my Juki 2000 but I'm sure it will sew up just as nicely. You can get Glide at some quilt shops but you can also order directly from them at
www.bobbincentral.com I had emailed and asked if I could get a sample before buying a bunch and they sent me a small cone of it and some of their magna glide bobbins. Love love love my Glide thread..
