Like any serger, the Husqvarna/Viking Huskylock 910 makes a great companion to a standard sewing machine. But unlike some basic machines, this one has a bit more to offer in terms of quality and features. Equipped with a 2/3/4 thread interlock system, this machine is topped only by machines with a 5-thread system. Unless extreme durability is called for, this 4-thread machine should be sufficient for most household uses. Husqvarna has added a number of features to this machine that make it more convenient to operate than some less expensive models. For example, Huskylock 910 has the sewing advisor feature. The sewing advisor suggests stitch lengths and widths for the job and recommends which needle to use, what tension to apply, and how to set the differential feed. It saves the user trial and error, and is useful for 11 different types of stitches and 6 varieties of fabric. The beauty of this advice is that once determined, it can be saved in one of 50 memories. Then it is ready to go each time you return to this task. On this machine, you're also paying extra for the differential feed. This feature keeps seams from stretching and puckering--a common problem with sergers. The differential feed is also useful for gathering. A solid-built machine, consider this one if the puckering of cheaper machines is bothersome or you need the extra guidance the sewing advisor can offer.
