It's hard to tell in the picture, but the design is of leaves, or diamonds. I can't imagine being able to write a pattern. Math was never my strong suit, and I'm pretty sure designing requires it. My mind doesn't work that way, lol. Although, I guess if you have been knitting forever, and know what kind of stitch will turn into what you want your design to be, then maybe it's a natural progression on the knitting highway. This pattern, by Linda Irving-Bell can be found on ravelry.com.
The bright tomato color of the yarn is fitting in nicely with my decision to move away from all of the blacks and blues of my closet. I'm breaking out of that mindset. Wheeeeeee!
