I have a Juki TL98Q and I have been machine quilting since 1999. I do meandering or stitch in the ditch, or straight quilting diagnonally. I have done 3 or 4 king size quilts and many queen size, but I find as I am getting older, and the tendonitis in my right arm flares up more often, that I am not doing as many of the big quilts anymore. I also use gloves to do the meandering. I use "16" Schmetz needles and one of three types of batting: 100% cotton; 80/20 Hobbs, and occasionally 100% polyester.
