    See price on AmazonSee it on Amazon

The hem on a store-bought T-shirt is a cover stitch: two or three parallel needle lines on top and a looper thread underneath that lets the seam stretch. A regular sewing machine twin needle can imitate it, but the stitches often pop or tunnel on knits. A coverstitch machine does it properly. The choice is between a dedicated coverstitch machine, which does cover and chain stitch only, and a machine sold as a coverstitch serger, which adds more thread programs in one body. What separates a good pick is the number of needles (three gives you triple cover), the stitch width, differential feed to stop knits from waving, and a free arm for sleeves and leggings. This guide compares each model by those facts as its listing states them, and flags what the listing leaves out.
