I created this Ducky for a friend of mine who is having a baby this winter. If you've ever looked for gender neutral baby gifts, you know it's hard! Duck and frog themed items are always a safe bet though.
I didn't follow a pattern, though I was inspired by a bluebird that I knit earlier this year (also no pattern). It's pretty easy to wing it (pun intended) if you know how to knit a sphere.
I wrote a bit more about my duck, bluebird and some other knitting projects on my blog if you're interested:http://ebretzel.wordpress.com/2010/09/19/isnt-that-ducky/
