Oh Oscar! the Grouchiest Hat ever!
The main color used was Red Heart Super Saver Solids in Spring Green, White for the Eyes, Black for the Irises of the eyes, all Worsted Weight.
The Eyebrows are made holding 2 strands together of Lion Brand Yarn Fun Fur (eyelash yarn), and sewn on w/ a strand of worsted weight chocolate brown yarn (I used Caron Simply Soft Eco in Chocolate).
When attaching the pieces, I like to angle the whites of the eyes going down from the middle, and place the black circles toward the middle of the face.
Note: Instead of knitting a flat circle for the black iris, you may also choose to crochet a circle. I do this sometimes instead.
*NOTE: There has been some confusion about the way I joined the rounds. When I wrote this pattern I didn’t know how to join rounds w/out knitting the first and last two stitches together, if you do this you should cast on one extra stitch.**
Otherwise, just cast on, join the round and work 1” in a k2,p2 ribbed pattern**
