How to Sew a Turtleneck

Turtlenecks have made an entrance back onto the fashion scene this season, and we are loving it. There is something so comfy, cozy, and warm about the thought of turtlenecks in the fall or winter. They make you want to snuggle up with a good book in front of the fireplace with a mug of hot cocoa. It’s easy to turn any basic shirt pattern into a turtleneck with this sewing tutorial. Customize the neck by making it as fitting, or loose, as you are comfortable with.

Skill Level: Beginner, comfortable working with knits
Time Needed: 1 – 2 hours

Step One: Sew up your main shirt pattern as instructed, leaving out the neckline binding.

Determine how fitted you would like your turtleneck to be. For a more classic fitted neckline, use rib knit fabric and measure around your actual NECK and add 2” for ease and seam allowance.

For a more cowl neck, draped turtleneck, measure around the shirt pattern neckline, and add 1” for seam allowance.

Step Two: Cut out turtleneck pattern, using your measurement from Step One X double the length of your neck. Make sure the stretch is going from left to right when you are cutting.

Step Three: Fold turtleneck in half, right sides together, pin and sew back seam.

Step Four: Fold turtleneck in half again, this time matching up the bottom raw edges and enclosing the back seam.

Step Five: Line up the turtleneck back seam with the center back neckline of your shirt. Pin around, pinning the raw edges together. If you are sewing a more fitted neckline, then you will need to stretch out the rib knit as you pin / sew to match the shirt’s neckline.

Step Six: Sew using a serger, zigzag, or stretch stitch. Press seam down and edge stitch with a long straight stitch to secure seam in place.

And you are finished! Stay warm this winter in style.
