About the time I quit doing a lot of dress making , I bought a Bernina serger. I use it a lot just finishing things like making rolled hems for napkins, valances etc. It sometimes now is used more than the sewing machine. Knit tops it is great. If there is a possible way to use it, I do. Many quilt tops are serged as it is so much faster when doing a lot of straight stitching. For the charity quilt pattern I use, it makes it come together in no time. Mine is just one of the cheaper models from a few years back and it has been heaven having it. How I managed to sew little girls dresses and hubby shirts without one, I will never know. Whatever one you end up getting you will use it a lot . Mine is not a self threader so if you buy a cheaper one, do not be intimidated by it. Once threaded it is easy to change thread. :thumbup:
