To make this pattern even more fun, I’ve designed the bags in both an adult and a child size. The pictures for this tutorial feature the child sized bag (the blue shark), but the construction techniques are the same for the adult sized bag (the gray shark) as well. The child instructions are written out first (illustrated with pictures), followed by the adult instructions. So follow along and make your own unique bag! It’s guaranteed to be a conversation piece.

Child Size
Materials:

• Worsted weight yarn in main color (I used less than 1 skein of Loops & Threads Impeccable)
• A small amount of worsted weight yarn in white for teeth and black for eyes
• Size I (5.5mm) crochet hook and size H (5.0mm) crochet hook
• Stitch marker (optional)

Body:
This section begins in the round (in a continuous spiral without turning or joining) in order to avoid a visible seam. I recommend using a stitch marker to help keep your place.

I hope that you enjoy this pattern! If you make a shark bag of your own, I would love to see it. And, as always, if you have any questions or comments about this bag you can reach me in the comments section below or on social media. I do my best to make all my patterns error-free, but there was a lot of copy-pasting on this one because of the two sizes, so if you catch any typos please let me know; you’ll get a gold star in my book 😉
