I've had my serger for about 10 years and I still get my book out when I thread it from the beginning. I usually just tie on the new threads and that is very easy. I bought a serger with a cover stitch; but find that I seldom use that feature. I really use my serger when sewing for my granddaughter. I make her turtle neck cotton knit shirts and bathing suits entirely on the serger. I also use the serger to make the rolled hems on the ruffle on her nightgowns. Of course, I use the serger for finishing seams, making napkins, etc. As for quilting, I have only used it to serge the cut edges of my fabric before I wash it. If my fabric has a serged edge, I know it has been washed. I love my serger and would not want to be without it.
