🌿 Eco-Friendly Crafting

What makes this crochet pattern eco-friendly and sustainable?

THE YARN: I use only sustainable and eco-friendly yarn that has been ethically grown/raised and processed, putting the people and the planet first. This is why I chose 100% natural yarn for this pattern.

HANDMADE FOR LONGEVITY: Creating your own seahorse plushie promotes mindful consumption. This durable, handmade toy reduces the need for mass-produced alternatives.

THE SLOW YARN MOVEMENT: I’m participating in the Slow Yarn Movement. There’s far too much to talk about here, but please take a few minutes to learn about what this means by reading the article I wrote about the Slow Yarn Movement as part of my 6-part Sustainable Crochet Series.

If you’re interested in learning more about sustainable crochet you can read all about it in the 6-part series I wrote covering everything about Sustainable Crochet and how to implement it into your own crafting starting today!

Meet Yoyo the Seahorse:

Down deep in the sea where the blue waters swayed,
Lived Yoyo the seahorse who drifted and swayed.
She twirled with the tides in a wobbly soft way,
But wished she could zoom like the fish every day.

The dolphins went SPLASH and the tunas went ZOOM,
They darted past coral — vroom vroom vroom vroom!
While Yoyo went wobble… and wiggle… and slow,
“Oh why am I different?” she whispered so low.

“I try and I try but I just can’t be fast,
I’ll always be last while the others zoom past.
If only I swam like the rest of the sea,
Then maybe — just maybe — they’d notice poor me.”

She drooped in the kelp with a heavy, sad sigh,
When Old Turtle drifted slowly drifting on by.
“Dear Yoyo,” he said with a warm gentle grin,
“Why wish to be someone you’ve never been?”

“The sea needs your softness, your curves and your sway,
Your gentle slow dancing brightens each day.
Not everyone’s made for a hurry and race,
Some shine by moving with calm and with grace.”

So Yoyo tried drifting instead of feeling small,
She twirled with the tide like a ribbon in fall.
She floated past coral in loops soft and bright,
And suddenly felt something sparkle inside.

The fish gathered round with a gasp and a cheer,
“Yoyo! You’re beautiful when you drift near!
We love how you move — you glow when you sway!
You make the whole ocean happier each day!”

Yoyo smiled wide from her nose to her tail,
She didn’t need changing to finally prevail.
For being herself was already enough —
And that made her strong… kind… and wonderfully tough.

Not everyone is meant to race —
some of us are meant to dance with the waves. 💙

At this point, with a strand of yarn and a tapestry needle, I took a few stitches up and down through the neck to help it curve more dramatically and fastened it off on the inside. Also, at this point, make sure your starting point for each row is centered on the back of the neck. If it’s not centered, give or take a few single crochets at this point to do so.

Sl st to fasten off. Cut yarn leaving a 2 ft (24″) tail which will be used for curving the tail. Weave through front loop of remaining 6 stitches and pull tightly to close.

Now, let’s curl the tail on your seahorse crochet pattern: using a tapestry needle and the long yarn tail, weave the yarn behind/under the post stitches up the center front of the tail, weaving your needle behind each of the posts in each row – ending back at about row 107 (36 rows from the tip of the tail) Pull on the yarn tail and watch the tail curve up!

Now, take the needle and push it through the thickness of the tail from inside to outside and back in a couple times to secure the curl. Take a couple stitches on the inside of the curl to secure the end and pull the yarn to the center and cut.

The Fin

TIP – Picot stitch instructions: chain 3, sl st into the back bump of the 3rd chain from the hook

Row 1: fsc 108, ch 1, turn

Row 2: (picot in next st, sc in next 3 st) x15, sc in next 10 st, ch 2, turn

Row 3: inc in next st, dc in next 8 st, 2 dc in next st, ch 1, turn

Row 4: inc in next st, sc in next 10 st, inc in next st, ch 1, turn

Row 5: inc in next st, sc in next 12 st, inc in next st, ch 1, turn

Row 6: (picot in next st, sc in next 2 st) x7, picot in next st, sc in next st, sc down side of fin back to chain, sc in next 3 st along the chain, (picot in next st, sc in next 3 st) x7, (ch 2, sc in same st as current sc, sc in next 3) x10, sl st in final 2 st

Fasten off, leaving a long tail for sewing on the fin.

Assembly

Starting with the end of the fin, start pinning it in place, beginning at the end of the curled tail. Pin fin along the back, keeping it centered and ending on top of the head – just above and between the eyes. Use the long tail yarn and a tapestry needle to sew on fin, weaving it through every stitch on the fin on each round of the body. Be sure to weave it under the POST of the stitch, rather than just the top loops, which will ensure a more secure attachment. When you get to the opposite end of the fin, weave back through 5-6 times. Bring the yarn to the inside of the seahorse and cut.
