At last I have finished writing up the pattern for my Sunkist Cardi. I know I promised it over a month ago, but I'm easily distracted!
I've only done the pattern in one size, 34". I made it with negative ease, my bust measurement is 36". Since it's knit as a topdown raglan, it should be pretty easy to modify to your own size. For a good formula for topdown raglans follow this link.
This is the first time I've written up a pattern for other people to knit from. If you find any errors, unclear instructions, or have any other thoughts, please let me know. Also, if anyone actually knits this, I would love to see photos. I will link to them or post them here.
The pattern is in the sidebar. Enjoy!
