I have a Janome and use it to finish the ends of my quilting fabric before I wash it. I hate all of those loose stringy threads in my washing machine. I also use it to finish the edges of my quilts before I put the binding on. I use the rolled hem for linens (and I have a ton of those). Other than that, not so much. I guess I could probably live without it. If I ever get another one, it will be self-threading. I didn't want to spring for the extra $300 when I bought this one, but I would do it in a heartbeat if I had to do it over again. Threading it is a real pain!
