Mermaids are mythical, magical creatures that always bring a smile to your face. Perhaps the only thing more likely to do is a rainbow-combine the two and you've got a practically perfect pattern!

This crochet pattern uses a shell stitch that looks a lot like the scales of a mermaid. In addition to crochet shell stitch, this pattern uses post stitches as well as basic stitches, including double crochet.

What's really neat about this crochet pattern is that it's designed as a classic mermaid tail blanket, but it can also be adapted to wear as a scarf.

Extra chunky yarn and a large size Q crochet hook means that this crochet mermaid tail blanket pattern works up really quickly. Vertical ribbing enhances the design and makes for a particularly warm lapghan.

This surprisingly simple crochet mermaid tail blanket is made using almost entirely double crochet stitches, including some worked in the back loop only. The ruffles at the top add a creative flair to the design and also help to keep you comfy as you use the blanket. This free crochet blanket pattern is made using self-striping yarn. It comes in five sizes for all ages, and it is available as both a written pattern and a video tutorial. It begins with a magic ring, and there are links to tutorials for those who aren't familiar with starting in the round using that technique.

Cuddle up and read your favorite book while tucked into this warm crochet mermaid tail blanket. The pattern is a simple design of single crochet and double crochet stitches, with strategic decreasing that creates the tail shape. This free crochet pattern is written for three sizes (child, teen, and adult). It is available as a written pattern as well as a video tutorial.

An adorable crochet mermaid tail is the perfect choice for a baby's first costume or summer photos. As they get a little older, young children also enjoy playing dress-up with this type of outfit. This crochet pattern covers all of those bases, because it is available in eight sizes from newborn through approximately age 5.

There are two styles to the pattern. Most of them have a bikini top that matches the mermaid tail, which is fairly classic for this type of design. However, the smallest sizes comes as a one-piece with the faux bikini top attached, because this slips more easily over a fussy newborn to quickly take photos. It's a practical twist made by a smart designer.

The bikini tops for this pattern have a cute floral design. As a bonus, there is a matching floral crochet headband pattern for all ages.
