I started looking online for patterns, but couldn't find anything that I liked. So I decided to fall back on one of my personal crochet mottos: if you can't find what you want, just make it yourself!
You can customize this whale with any color or weight of yarn that you'd like to use, since gauge doesn't matter as long as you're consistent. Just adjust your hook size as needed to make sure that your stitches are tight enough to keep the stuffing in.
If you end up making one of these little guys, I would love to see a picture of how it turns out! You can reach me on Twitter, Facebook, Ravelry, or by email. Or, if you'd like to purchase a pre-made whale, take a look at my Etsy shop. And if you have any questions about the pattern, please let me know! This pattern has been tested (thanks to Mnemosyn, krissy7575, and Fierdre), so it should be error-free, but if you have any difficulties with it I'd be happy to help you out.
