In addition to blankets, the mermaid tail design can be crocheted into scarves, tote bags, washcloths, and other accessories. These patterns offer whimsy for everyone to enjoy!

    Crochet Mermaid Tail for Babies & Children

    Crochet Mermaid Tail Pattern

    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.

    The highly textured crocodile crochet stitch is a popular choice for mermaid tail patterns because it looks just like scales. It is used in this crochet scarf pattern, where it creates a very warm accessory that is finished off with more basic stitches to create the tail design. The scarf is designed for an average size of approximately 7" x 56" but includes instructions for making it shorter or longer to suit the size desired.
