How to Use a Twin Needle on Your Sewing…

Video class

This video is for members

Join Lulu Ferris to watch the complete class and sew along at your own pace.

What you’ll make

Learn to sew two parallel rows of straight stitching on the right side, with a zigzag formation underneath. This twin-needle finish adds stretch to hems on knits, sweatshirts and similar garments.

The demonstration uses a domestic sewing machine and explains how to recognize a compatible needle by its flat back and rounded front.

What you’ll learn in this class

Choose among universal, stretch and jeans twin needles.
Read package markings for needle spacing and needle size.
Install the twin needle in the correct direction.
Route two upper threads through the same path and thread one needle with each.
Test on a scrap of the project fabric before sewing the garment.
Assess tension by checking for the correct zigzag underneath.
Use the machine’s free arm to sew a circular knit hem when available.

A good sample has two even parallel lines on top and a clear zigzag beneath. If the underside does not form correctly, continue adjusting and testing the tension on matching fabric.
