Every little girl dreams of being a mermaid! My little girls have been begging me to sew up something special for them for the past few months! I finally caved as we were browsing the fabric aisles and JOANN and I came across the reversible sequin fabrics. It’s absolutely dreamy and I really couldn’t pass up the opportunity to sew with it. Maybe I’m reliving all of my childhood dreams of being a mermaid because I even made an adult sized version, but can you blame me?

Mermaid Tail Blanket Sewing Pattern

In this tutorial, I’ll share my tips and tricks for sewing with sequins and other specialty fabrics as well as the free pattern for the mermaid tail! I can’t wait for you to sew a mermaid tail, you are going to love it!

How to Sew a Mermaid Tail Blanket
Supplies

Let’s get started! Here is the measurement chart for each size. Each Mermaid tail will require two pieces of fabric for the main body.

Adult 54″ wide x 60″ tall

Child 45″ wide x 50″ tall

Toddler 36″ wide x 36″ tall


Begin by laying the fabric out on a large table and fold it in half lengthwise.

Adult 18″

Child13″

Toddler 10″

The mermaid tail will be cut so that the bottom of the tail is smaller than the top of the tail. Start by referring to the measurement chart above. The mermaid tail shown in the photos is a toddler-sized pattern. From the folded edge measure 10 inches and mark the fabric. Draw an angled line from that point to the top corner of the fabric. Use a fabric pen to draw in the cutting line.

Follow the cutting chart below for the specific size you are planning on making

Cut the fabric along the marked cutting line. You will be cutting along the side with two raw edges. Once the fabric is cut you will be left with a straight side that’s folded over and one side that’s angled.

Repeat this process with the lining fabric.


For the mermaid tail shown in the photo tutorial, I used two layers of plush fleece for the body and reversible sequin fabric for the tail. You can switch the placement of the sequin fabric to the main body if you would like to replicate the green and blue mermaid tail.

Open up both mermaid tails and lay them on top of each other with right sides together. From the top of the tail sew a straight stitch halfway down the tail, repeat this on the opposite side Leave the bottom half of the tail alone until the next step.

 


Open up the tail so that the unsewn portions are separated. They should be facing each other and pinned together.

Sew from one side of the tail up to the point where they meet and down the opposite side. Your tail should resemble the photo above with the tails being sewn separately.

Tuck the pink tail inside of the white tail and flip them right side out. The raw edges should be concealed inside of the tail.

Print the mermaid tail template and lay it on top the fabric that you will be using for your tail. The fabric should be folded in half and the edge of the pattern should be aligned with the fold of the fabric.

Cut around the pattern, then repeat this step until you have a mermaid tail front, back and a layer of cotton batting.


Layer the three pieces of fabric so that the mermaid sequin fabrics are facing each other and the batting is on the bottom.

Use plenty of pins to secure the pieces of fabric together.


Sew around the bottom and two sides of the mermaid tail leaving the top of the tail open for turning. Trim down the seam allowance.

Grab the layer of mermaid sequins furthest from the batting and turn it right side out.

Turn the mermaid tail upside down so that the fins are facing upwards. Fold the fins inwards and slide the tail inside of the body of the mermaid.

Make sure that your lining fabric is facing outwards so that the pink fabric is facing the tail.


Sew through all the layers to attach the mermaid tail. Serge or zig zag stitch the raw edges.

Turn the mermaid tail right side out!
