Singer Simple 3337: Basic Sewing Made Easy
The Singer Simple 3337 is a mechanical sewing machine with 108 stitch applications, a built-in needle threader, and a drop-in bobbin. It arrives pre-threaded, with the accessories stored in the front compartment, so you can start sewing right out of the box. The machine suits crafts, simple home decor, and fashions, with a heavy duty metal frame and 6.1 inches of sewing space.
Singer's Online Owner's Class covers threading, stitch selection, and making a buttonhole, and the SINGER Sewing Assistant App covers machine parts, set-up, and stitch selection.

108 Stitch Applications and One-Step Buttonholes
Choose from 108 stitch applications for basic, stretch, and decorative sewing, built from 29 built-in stitches. Buttonholes sew in one easy step: place the button in the buttonhole foot and the machine sizes the buttonhole to fit.

Easy Dial Stitch Selection
Turn the stitch selector dial to the stitch you want, and adjust the stitch length to suit the fabric. A reverse lever locks seams at the start and end, and snap-on presser feet are easy to remove and attach.

Drop-In Bobbin and Free Arm
The top drop-in bobbin sits under a clear cover, so you can see how much thread is left. Place the wound bobbin in its holder and follow the marked threading path. The machine picks up the bobbin thread when you start sewing. Slide off the storage compartment to reach the free arm for trouser hems and sleeve cuffs.

Marked Threading Path and Built-In Needle Threader
The built-in needle threader saves eye strain, and the threading path is clearly marked on the machine.
Five presser feet are in the box, including the Sew Easy foot with an adjustable guide for straight seams, along with a darning plate for free-motion work, an edge/quilting guide, needles, and Class 15 transparent bobbins.
