How I crocheted my mermaid tail blanket



Oh my goodness, I am feeling like Ariel with my latest crochet creation! My six-year old self would be extremely pleased.

If you want to recreate this blanket the first thing you are going to need is patience, the second thing is a keen eye, and thirdly you’ll need the list of things I used, which are below.

You’ll need: 

  • 6mm (J) crochet hook (for the tail)
  • 6.5mm (K) crochet hook (for the fin)
  • scissors
  • yarn needle
  • 6 skeins of worsted weight yarn. I used Red Heart Super saver in Macaw which I bought in-store from Walmart however it’s also available on 



For the tail: 

The stunning shell stitches, created by double crocheting five times in a stitch every two stitches, is what initially drew me to this video by YARNutopia by Nadia. Plus the construction is explained in such detail that makes it perfect for a beginner or intermediate crocheter. I didn’t want to switch colours every round so I just used one ombre colour throughout and it still looks fantastic.


The beautiful shell stitches

Note: I am 5ft 5″ and I used the LARGE pattern. Round 75 onwards is still the same as round 67 onwards in the Medium pattern so you can still follow along with the video.

For the fin: 

Note: I used a 6.5mm crochet hook for the fin.

I decided that I wanted a larger, more defined fin for my mermaid tail so I turned to a video uploaded by Annoo Crochet Designs. The fin tutorial starts at 14.43. My fin didn’t 100% go to plan. One was slightly larger than the other and I didn’t finish my stitch in the same place as Annoo. It was late at night and I was watching TV at the same time so I probably just messed something up. It was very easy to rectify though and in the end my fin looked fantastic.

User, Surekha Singh, in the comments had typed these up:

Pattern for fin (crocheting in rows)

  • Make a slip knot and 51 chains
  • Round 1: hdc in 2nd chain from hook, hdc in next chain*, chain 1, turn around
  • Round 2: hdc in back part of stitch*, stop 3 stitches from the end, chain 1, turn around.
  • Round 3: hdc in back part of stitch*, chain 1, turn around
  • Repeat Rounds 2 and 3, until you have 22 rows
  • Make 2 of the above (for both halves of the fin)

Watch the video for putting the fin together and attaching to the tail.

Here are some of the pictures that I took as I was going along: 

This is Sable, my schnauzer puppy, eyeing up my yarn! She grabbed it at one point and tangled the whole thing up. However, she’s since learned to keep away.

Don’t forget to turn the fin/tail over when you are attaching the fin to ensure there are no holes like the below example.
