If you have been wondering how to make a DIY sleeveless turtleneck sweater, this is the tutorial for you! Sleeveless turtleneck sweaters are elegant and basic.

This gorgeous foundational piece is seasonless. You can wear it in the winter under a jacket, sweater, or blazer. You can wear it in the summer as is. It is the perfect top!

Here’s how to make a sleeveless turtleneck top...

Tools and materials:

I’m using a fleece-type stretch fabric for this tutorial. Whenever you use a stretch fabric, check to see which way the stretch goes.

Sleeveless turtleneck sewing pattern

1. Prepare the fabric

Download and print the pattern. The Azania pattern has many options. We'll be doing View K.

Cutting out the sleeveless turtleneck pattern

Cut out the pattern pieces for the sleeveless turtleneck top. You should have a front, 2 back pieces, and a turtleneck piece.

For the front piece, make sure the center is on the fold and the stretch goes across the body before cutting. 

Don’t forget to mark out the notches where indicated when cutting out the fabric.

Pinning the back pieces together

2. Start sewing

Start with the back. Place the two back pieces right sides together. Pin along the center back.

Zigzag stitch the back, leaving a ½-inch seam allowance. Don’t forget to backstitch at the start and end of the seam for extra security and strength!

Don’t stretch the fabric as you sew. Simply guide the fabric through. 

Pressing the seams open

After sewing the back, press the seam. It’s hard to press a zigzag seam open, so press to one side.

Now, align the front and sewn back piece. Lay the front piece on top of the back piece so the right sides are together. Pin at the shoulders. Sew with a zigzag stitch. Press the seams.

Line up and pin the side seams in place. Sew them with a zigzag stitch. 

Hemming the DIY sleeveless turtleneck

3. Hem the bottom (optional)

This step is optional if the fabric you’re using doesn’t fray. Hemming does leave a nice professional finish though.

If you want to hem, fold the fabric from the bottom on the wrong side from ½ to 1 inch. Pin and then stitch in place.

Folding the turtleneck collar piece

4. Attach the turtleneck collar

Fold the collar piece in half so the right sides and the short sides are together. Sew across the short side using a zigzag stitch with a ½-inch seam allowance. 

Once the loop is sewn, fold the collar in half widthwise so the sewn seam is inside and the right side is facing out.

Slip the neckline into the collar. Then, match the seam inside the collar to the back center seam. Pin in place. Pin the center front in place. Then pin all around the neckline. Sew with a zigzag stitch.

5. Finish the armholes

Choose whichever armhole finish works best for you. You can fold in the edges of the armhole about ½ inch to the wrong side. Pin in place and then sew it down.

Finishing the armholes with bias tape

The other way is to use ½-inch bias tape. Place the bias tape on the right side of the armhole. Pin in place. Overlap the ends and cut off the excess. 

How to finish the armhole with bias tape

Sew at the first fold using a straight stitch.

Pinning the bias tape to the armholes

Then, turn the bias tape towards the wrong side. Pin in place and sew down. Do to both armholes.
