Crochet Seahorse Applique and Granny Square Free Crochet Pattern - Ocean Themed Blanket


The Seahorse is the 7th square of my Ocean Afghan. To find all the information about this Afghan click here.

I'm so happy to share with you this little seahorse! Doesn't he just remind you of a ray of sunshine?

I chose to make him the typical yellow seahorse, but once I used a different shade for his outer edging and fin I immediately thought - how cute would this be if it were a yellow and pink seahorse? Or a blue and yellow one? I hope you guys get creative with the colors because I'd love to see the outcome!

I can already see this afghan coming together as I've started to lay down some of the squares for arrangement. I've shared on Instagram and Facebook a sneak peek of what it will look like. It's a sneak peek for me as well! All the colors are coming together so nicely and I'm motivated more than ever to keep these designs coming!
