Craft Alotl is BACK with another wonderful easy crochet pattern for you! Today, she shares her dress up amigurumi crochet mermaid doll! You can change her outfits from mermaid doll to land doll. So cute! As with all the Craft Alotl patterns here on Red Ted Art, you can either read them on this website or if you want them ad-free/ want to support a young creator, you can purchase them from her Ravelry store! Each time she makes a sale, she makes a little happy dance and is motivated to create more for you. You can also Learn How To Crochet with Craft Alotl!

So this little mermaid crochet pattern is part of the Ellie & Friends series. Once again the patterns mix and match. Be sure to stay consistent with your crochet hook size, as that can impact the final size of your doll. The mermaid is not part of the Ellie & Friends bundle YET! But we will be adding her soon. Those eagle eyed will see that the mermaid doll is wearing Ellie’s dress! Which of course is the whole point of mixing and matching. And the Ravelry price reflects this!

This is a lovely doll to make for a little girl or boy who adores mermaids! We HAVE a crochet mermaid pattern here on Red Ted Art already – but they are larger and you can change them into clothes.. but they are just as cute and you may want to take a peak:

I think either mermaid doll makes a lovely gift and it just a question of preference! Both are free crochet patterns for Red Ted Art readers! As mentioned, you can print Craft Alotl’s mermaid crochet pattern via her Raverly Store:

06: (4 sc, inc) x6 [36]

07 – 11: 36 sc [36]

12: attach long hair

You will need to cut a number of strands the same length. If in doubt, make the hair longer and trim it later! Do this by wrapping the yarn around a rectangular shape and cut. Each length needs to be twice the length you want the hair, as you need to hook them through the hair cap:

To attach the yarn to the cap, put the hook through a stitch (as you would for a crochet stitch), fold the yarn in half, and using your hook, pull the yarn through the stitch. Make sure there is a loop, so you can now pull the tail ends through and secure it.

Once you are done, style and trim the hair. Sew cap to head.
