Singer M3330: 97 Stitch Applications for Everyday Sewing
The Singer M3330 is a portable, mechanical sewing machine in blue with 97 stitch applications for basic, stretch, and decorative sewing. Stitch width and length are adjustable, so the same machine handles fabrics from sheer to stretch knit to denim. It suits crafts, garments, home decor, and mending.
A built-in needle threader, one-step buttonhole, and heavy duty metal frame come standard, with 5.7 inches of space to the right of the needle.

97 Stitch Applications and Dial Selection
Choose from 97 stitch applications built from 23 built-in stitches. Turn the stitch selector dial to the stitch you want, then adjust stitch length and width to suit the fabric. A reverse lever secures seams at the start and end.

Free Arm and 5.7 Inches of Space to the Right of the Needle
Slide off the removable storage compartment to reach the free arm for sleeve cuffs and trouser hems. The 5.7 inches of space to the right of the needle and the 4.2 inch workspace height give room for larger projects.
One-Step Buttonhole and Needle Threader
Place the button in the buttonhole foot and the machine sews a buttonhole sized to fit in one step. The built-in needle threader threads the needle eye for you and saves eye strain.

Portable Metal-Frame Design
Inside, the frame is metal for long-lasting durability, and the machine weighs 13.6 lbs for easy moving. A handle makes it simple to pick up and carry. LED lighting stays cool to the touch, and one switch turns on both the power and the light.
Front-Loading Bobbin and Snap-On Feet
The front-loading bobbin uses Class 15 transparent bobbins, so you can see how much thread is left. Snap-on presser feet come off and go on quickly, and the extra-high presser foot lifter makes room for thick fabrics.
Four presser feet are in the box, along with a darning plate for free-motion sewing, an edge/quilting guide, needles, and Class 15 transparent bobbins.
