Mermaid pattern c2c square

Ok, I know, I know – Mermaids aren’t real so why in the world am I adding one to my Sea Life themed throw?? Well, I really wanted to add a small touch of whimsy to my blanket. And, if you are making this for a little girl that loves the sea – she is going to love it! And, you could even make the mermaid match the little girl – change up the hair and eye color so she can see herself swimming amongst all of her sea life friends. 💕 And, of course, every square is optional, so just substitute with something else if you would like.

I used the mini-hdc c2c crochet technique for this square and I ended up with a 9″ x 9″ square. You could certainly choose to use the standard dc technique which would give you a larger square. However, at 9″x 9″ this would be the perfect size for a whimsical summer themed dish cloth, too!

I used Yarnspirations’ Caron Simply Soft yarn for my squares – I love how soft this yarn is which is perfect for blankets. However, you could certainly substitute your favorite medium worsted #4 weight yarn to get a similar result.
