Free Mermaid Dishcloth or Afghan Square Knitting Pattern

Our latest creation is a free knitting pattern for a Mermaid Square!

This square would work great as a washcloth or dishcloth , or you could put it together with some of the other squares to make an afghan. There are many nautical themed squares, including whale, lighthouse, mermaid, octopus, seagull, narwhal, fish, whale’s tail, seashell, crab, starfish, shark, penguin, clam shell, boat, turtle, palm tree, anchor, dolphin and seahorse. You can find all of the nautical themed squares here – together they would make a fantastic nautical themed afghan! And if you wanted to make a fantasy themed afghan, there are other fantasy themed squares here.

By using these link, and at no extra cost to you, I may earn a small commission which helps to support the production of more free patterns and the purchase of yarn for several charity knitting groups I belong to.

For this square, I used Cascade Yarns 220 Superwash Yarn in Duck Egg Blue– I absolutely love this yarn, it’s 100% wool, machine washable AND can be tumble dried (so great for baby blankets)! The wool is also very soft, and knits up with wonderful stitch definition, which is fantastic for these squares. If green isn’t your choice of colour, no worries, as 220 Superwash comes in an amazing 135 different shades! One ball makes 3-4 squares using 3.5-4.0 mm needles.

Size and Materials

Size depends on yarn and needle size used:

With DK/Light Worsted Weight yarn and 4 mm (US 6, UK 8) knitting needles, finished squares are approximately 22 cm x 22 cm (8.5 inches x 8.5 inches)

With Worsted Weight yarn and and 4.5 mm knitting needles (US size 7, UK size 7) finished square is approximately 26 cm x 26 cm (10 inches x 10 inches)

Any sized needle and yarn can be used (please refer to yarn label for recommended needle size), however different needle and yarn sizes will produce different sized squares, so if you plan to make an afghan or a set of these it is best to use the same needle size and yarn for each square.
