The patterns are from the book "A Crochet World of Creepy Creatures and Cryptids: 40 Amigurumi Patterns for Adorable Monsters, Mythical Beings and More". I bought it from b&n, but this is the link to Amazon.
They are Acrylic yarn, and a 3.75mm hook. I think the recommended size was 4.5mm but I could be wrong.
I feel that! 😂😂😂 I have so many patterns I’ve bought and still haven’t gotten around to using! I got an email from Amazon recommending crochet books and I’m having to fight the urge to buy a few of them! (Although I think will seriously pre order this one )
