I received my serger as a gift from my husband a couple of years ago. I was determined to learn to use it and have done so with the help of a very knowledgeable dealer who knows every aspect of sewing and quilting. I don't know what I'd do without it.
However, one difference I see with all the other commenters is that I have wanted to learn (and am learning) sewing of garments. I didn't learn to sew as a youngster, but have now developed a desire now that I am in my sixties.
