I used a size 3.75mm hook and some left over yarn from a pair of socks I knit last year, it's Spun Right Round in Graffiti. It's a super busy yarn, so you can't really see all the stitch definition but I still think it looks great. The eyes don't photograph very well, they don't really look right but in real life they look perfect. For the sticks, I trimmed down a couple of bamboo skewers. The finished size of the owl, including the fringe is 7.5 inches. Seriously cute!
There's quite the size difference between my first and second owl, I love it. My first owl's fringe is a lot more frayed than it was when I first made it. Our cat used to love jumping at it as a kitten, that thrill has worn off thankfully now though, he just stands up and reaches it easily, less fun.
The pattern I used can be found here on ravelry.
P.S. Happy first day of Spring!
