This is a digital crochet pattern for a cute amigurumi triceratops dinosaur.
The pdf file includes a written crochet pattern to make the dinosaur, as well as an extra crochet chart for the triceratops frills. There are detailed assembly instructions and lots of photos.
Exact gauge is not important. Medium weight yarn and a 3.5mm (E/9) crochet hook will make an amigurumi that is approximately 2" / 5 cm long. However, the pattern will also work with thicker or thinner yarn.
