92.2 The Janome Sewist 721 is a reasonably affordable mechanical sewing machine. It is a good fit for both the beginner and the intermediate sewist. The 721 sews smoothly and is quiet. Owners like that the unit is fairly lightweight, making it a respectable choice for taking to classes or sewing events. It is also easy to use and the manual is well written and easy to understand. However, there is a lot of plastic in the 721 construction and the unit has a limited number of features.
