This downloadable e-book contains crochet patterns for seven different amigurumi animals: a blue whale, dolphin, manatee, narwhal, orca whale, seal, and walrus.
The pdf file includes 18 pages of written crochet patterns, step-by-step photos, detailed assembly instructions, and printable templates for the felt details.
This pattern collection is perfect if you're already familiar with the basics, and want to learn some new amigurumi-making skills.
Using medium (worsted) weight yarn and a 3.5 mm (E) crochet hook, your marine mammals should be about 4 cm / 1.6" wide. You can adjust the size by using thicker or thinner yarn. For animals with felt details, you'll need to adjust the felt template to match.
