Almost all commercial sewing is done on a serger or at least most of it. While I don't garment sew all that much anymore I use it to make my Linus quilts. I make them pillowcase style and sue the serger to do the initial joining of the two layer and the batting. I then turn it right side out, press it and machine quilt it. I have recently started making the little dresses that are sent to the Carribean to cover the little girls to help keep them safe. I serge all of the raw edges of the material I use on the dresses. It gives them a professional look that makes the children think they are "store" bought just like the "rich" girls. This is my second serger. I had a basic Bernina one for about twenty years. I used it a lot making garments and crafts for my daughter and grandaughters including the dresses for my daughter's wedding. Last year I traded up to a little more efficient one that was much easier to thread. It gets used as often as my sewing machine.
