Size: approximately 1” x 4.5” length will vary depending on yarn used, and how long you leave the fringe tail.

Gauge: Not necessary for this pattern, though the size will change depending on what yarn you use. You can use any size 4 or 5 yarn for this project. If using a size 4 yarn you may want to size down your hook to a 5 or 5.5mm.

Please read through the terms before starting, there is a special stitch in this pattern, it is a variation of a Cluster-V Stitch.


ch = chain

sc = single crochet

slst = slip stitch

st(s) = stitch(es)  

Cluster-V Stitch: In the SAME space, Double crochet 3 stitches together, ch1, double crochet 4 stitches together all in the same space.

In this pattern the Ch2 at the beginning of each round counts as part of the cluster-v stitch. Because of this, you will do different number of stitches on each half of the cluster-v stitch.

Chain 4 and join with a slst to form a ring. Ch2 and turn.

Row 1: Cluster-V stitch into center of the ring. Ch2 and turn.

Row 2: Cluster-V stitch into the ch1 space. Ch2 and turn.

Row 3: Modified Cluster-V Stitch into the ch1 space (Modified Cluster-V stitch = Double crochet 2 stitches together, ch1, double crochet 3 stitches together in the same space). Ch1 and turn.

Row 4: skip the ch1 space and slip stitch into the next st.

Pull yarn and bring down through ch1 space.

Finished tail before adding the fringe.

You can also crochet the top part of the keychain right onto a key ring, just tie the yarn onto and keyring and ch2, then start on Row 1 working the cluster-v stitch into the keyring instead of the ch4 ring. When you finish the tail, use the yarn that you tied onto the keyring to wrap around the first cluster-v stitch then weave in the yarn tail.

Cut 4″ – 5″ strips of yarn, I like to cut 12 pieces. Insert yarn pieces a few at a time through the ch1 at the end of the keychain until you have put all pieces through.

Using the yarn tail from the top part of the keychain, wrap around the fringe to create a tassel. Then split the tail fringe in half and wrap the yarn tail around the middle, bringing the yarn up the wrapped yarn, and back down through the wrapped yarn on the backside.

The yarn tail splits the fringe in half making it easier to find the middle of the tail. Using sharp scissors trim tassel fringe at an angle.


If you didn’t crochet right into the key ring you can attach the mermaid tail to the key ring using a leather tag and Chicago Screw or Rivet. I use Chicago Screws and small vegan suede tags to attach mine. The tiny vegan suede tags used in this post are available in my Etsy Shop. I also have vegan suede tags that you can use to attach the mermaid tail onto the key ring.

I hope you find this tutorial easy to follow! I also have a complete packaging set in my Etsy Shop that works perfectly and designed to go with this keychain!

If you have the time I would appreciate it if you would visit my Etsy Shop, sales on tags and other printables help me out a lot so that I can keep adding free patterns like these on my blog. I choose to not have pop up ads, I love not having ads all over my site, I don’t want to add ads other than a few affiliate links here and there to my posts as I think ads really ruin the viewing experience. I am hoping if I can continue to make sales in my Etsy Shop to help me with my finances I can continue to add freebies to my site.

Thank you so much
