How to Sew a Chemo Cap FREE Sewing Pattern

Learn How to Sew a Soft Knit Chemo Cap With This Free Sewing Pattern With Children, Teens, and Adults Sizes. Step-By-Step Photo Tutorial and Video.

In honor of Breast Cancer Awareness month, I wanted to share this chemo cap sewing tutorial and free pattern. 

This is a sponsored post on behalf of JOANN. All thoughts and opinions are my own.

This chemo cap is made of a soft knit fabric for sensitive scalps. It’s comfy enough to sleep in while also being cute enough to wear out and about!

This hat can be used for cancer and chemotherapy patients, those with medical hair loss, or even alopecia.

It can even be worn just to keep your head warm in the winter!

This cap works best with a soft 4-way stretch knit fabric. Joann has a great variety of 4-way stretch knit fabrics. You'll want to look for a knit fabric that has at least 5-10% spandex. The spandex is what helps the fabric to keep its shape without getting stretched out.

I teamed up with JOANN, to bring you this pattern for free! JOANN is my one-stop shop for all of my sewing needs.

This pattern features six different sizes for babies, toddlers, children, teens, adults and large adults.

Chemo Cap Supplies

• 1/2 yard 4 way stretch jersey knit
• Serger
• 1/4" Elastic (.6cm)
• Sewing Machine
• Scissors or Rotary Cutter & Mat
• Thread
• Pins
• Iron & Ironing Board
• Needle
• Pattern

Step 1: Print and Assemble Chemo Cap Pattern

Download the pattern to your computer and print the pattern at 100% with no scaling.

You can print off the pattern on cardstock so that it will last for multiples uses.

Immediately check the 1” x 1” square to ensure the pattern has printed off correctly. If the 1" square measures larger or smaller the pattern will need to be reprinted for accuracy.

Align stars of each page and tape in place. Then, cut out the pattern in your desired size.

Step 2: Cut out Chemo Cap Fabric

Fold the fabric and align the pattern piece along the fold of the fabric. Cut 2 pieces.

Transfer the pattern markings to the fabric with a washable marker.

Cut 1 piece of 1/4"(.6cm) elastic

You should now have the following:

• 2 pieces of fabric for the hat
• 1 piece of elastic

Your fabric pieces should be folded in half (hotdog style). Press them along the fold with an iron.

Step 3: Sew the Hat

Fold one of the hat pieces in half. Sew or serge along the raw edge until reaching the marking.

If you are using a serger, leave a tail and thread the tail back into the seam.

Lay the newly sewn half down with serge ends facing up. Lay the other side right next to the first piece, raw edges facing up. 

Thread one end of the non folded side in through the little opening of the sewn piece. 

Make sure that the folded edges of both of the fabrics are on the bottom, like the photo shown above.

When pulled through, align raw edges, making sure they still face up at the top. Pin in place to mid markings.

Serge or sew the raw ends together leaving a tail.

Thread the tail into the seam if you are using a serger. 

Open the cap up and lay it out flat on the table in front of you. You should have two seam lines facing upwards.

Fold one side over to the other side (right sides together) aligning the folded edges along the bottom of the hat.

The seams should be on the outside of the hat.

Sew only along the bottom of the hat, leaving the top edge unsewn.

Pin in place and serge along the edge leaving a thread tail.

Weave the thread tail into the seam to secure it.

Pin the raw edges together alining the seams and sew along the side of the hat.

Step 4: Add the Elastic

Take the elastic piece and mark the middle with a fabric marker.

Align one end of the elastic with the top of the serged line you just serged.

Align the middle mark to the middle seam.

Align the other end of the elastic to the bottom seam.

Pull slightly on the elastic stretching it to fit the length of the seam and pin in between the top, middle, and bottom.

Using a long small zig-zag stitch, sew along one edge of the elastic, sewing it onto the seam of the hat. This will create a bunched look at the front of the cap.

Backstitch at the beginning and end of the elastic and cut any loose threads.

Your elastic should bunch up the fabric, if it doesn't bounce back to its original length, try hovering over the elastic with a warm iron to help it shrink back into its original shape.

Turn the chemo cap right side out.

Give the chemo cap a good pressing and you're finished!

Chemo caps can be donated to your local hospital, oncology unit, or infusion center.
