I have a middle of the road 4 thread Viking serger. I have used it for garments and home dec. But recently, I mostly use it to piece my quilt back, it trims off the selvage as it goes, "cutting" out an extra step. And, when I take a quilt off the frame, I run it through the serger to clean up the edges of the quilt, I find this makes applying the binding much easier. I would love to have one of the self threading ones, but given how little I use it now, it doesn't seem to make sense.
