This little hat is crocheted & is a lot of fun for baby to wear. It is a very simple project for someone just learning to crochet. I sold these hats on Ebay for 6 years, & am going to put them back up on my site. The book is called "Happy Hats" by Michele Wilcox & is put out by 'Needlecraft'. She has a total of seven hats of different animals & insects. Turtle, ladybug, pig, mouse, bear, bumble bee & snowman. I made so many of these hats that I think I could crochet one in my sleep!! I like to use a soft yarn as it is around baby's face & didn't want harsh yarn to be uncomfortable & scratchy.
