I did a practice piece in my serger class when I got the machine but haven't tried it since. I have a seam guide for my serger and I am sure wit a bit of experiemntation I could get a 1/4" seam. I think it would be very strong for childrens' quilts. My serger has 24 stitches, one of them a security seam that is a strong seam with overcasting. I might have to try it when I get my sewing room set up again. I have used my serger very little because I don't really have room for it. We will be moving soon and I will have a large bedroom that will be both a guest room and my sewing room, so I will have room to have more than 1 machine set up.
