SINGER · Sewing Machine

Helpful guidance for the early stages

Make the first steps of sewing feel more approachable. The SINGER Simple 3337 combines easy bobbin setup with a guided presser foot and 108 stitch applications for everyday garments, crafts and home accessories.

108 stitch applications
Sew Easy Foot included
Drop & Sew bobbin system

Helpful details for consistent seams

The Simple 3337 addresses two common setup tasks: following a seam allowance and bringing the bobbin thread into the sewing process. The Sew Easy Foot provides a guide to follow, while the correctly threaded Drop & Sew system picks up the lower thread as sewing starts. Neither replaces careful fabric guidance, but both can make practice more approachable. Use the free arm when a cuff or trouser leg is easier to position around a narrow machine bed.

Put the features to work

Follow a steadier seam allowance

The included Sew Easy Foot provides a reference beside the fabric edge. Use it while practicing simple garments or accessories where consistent seam allowance makes assembly easier. The guide helps you see the target; gentle, consistent fabric guidance still matters.

Simplify lower-thread setup

The Drop & Sew bobbin system is designed to pick up the lower thread when sewing begins after correct threading. The clear cover also lets you monitor the supply. Together, these features reduce two common sources of uncertainty while learning a new machine.

Features that make a difference

  • 108 stitch applications. Explore different practical and decorative techniques.
  • Sew Easy Foot included. Its adjustable guide helps you maintain a steady seam allowance.
  • Drop & Sew bobbin system. Follow the marked path without manually drawing up the bobbin thread.
  • Clear top drop-in bobbin. Check the lower thread supply as you work.
  • One-step buttonhole. Simplifies adding button closures.
  • Free arm. Access smaller tubular sections such as cuffs and trouser hems.

Questions about SINGER 3337

What does the Sew Easy Foot do?

Its adjustable guide provides a reference to help guide fabric along a consistent seam.

Do I need to draw up the bobbin thread manually?

The Drop & Sew system picks up the bobbin thread when sewing begins after correct threading.

Are stitch applications the same as built-in stitches?

No. Applications describe techniques you can perform with the machine's stitches. Compare built-in stitch counts separately when choosing between models.

Does the seam guide move the fabric for me?

No. It gives you a reference for the fabric edge. You still guide the fabric gently and keep the intended seam allowance aligned with the guide.
