Is the machine easy to thread?
Color-coded guides make threading easy, even without consulting the instruction manual. A lower looper autothreader eliminates tedious threading of guides under the stitch plate. The serger should be just as easy to thread using decorative threads—such as Wooly Nylon and Pearl Crown rayon—as with all-purpose serger thread.
Are the stitches well-formed and secure?
The stitches should lie flat, with the needle thread(s) holding the fabric pieces together securely.
Are stitch length, tensions, and cutting width easy to adjust?
Knobs should be easy to access, with clearly marked dials and settings.
Are there a variety of stitches for most techniques?
For instance: two-, three-, and four-thread overlock, flatlock, rolled edge, wrapped edge, coverstitch, and chainstitch formations.
Does the machine have a differential feed function?
Differential feed makes it easy to stitch knits without stretching, and is also useful for gathering, shirring, and making the fluted edges of a lettuce hem.
Does the serger have a built-in rolled hem?
The ability to change from overlock to rolled hem stitching with the flip of a switch makes it convenient to use both stitches in the same project.
Are cover stitching and chain stitching available?
These chain formations are excellent options for hemming and topstitching, giving the look of ready-to-wear clothing and adding a professional touch to your serging projects.
Is free-arm stitching an option?
The ability to slip a sleeve or pant cuff over the freearm makes hemming these small areas easy.
What accessories are included?
Some helpful accessories include tweezers, looper threaders, thread nets, spool disks, and seam guides.
Are accessories available for specialty techniques?
Other serger accessories include special feet for attaching beads and pearls, making and attaching covered cording, applying elastic, stitching blind hems, heirloom serging techniques, and creating fishline and wired edges.
