Not only are diatoms awesome in and of themselves, but their complex shapes prompted me to learn some interesting lacework techniques in the quest to approximate them in yarn, which I wrote about here. Also, I had a great time constructing the radiolaria. I think you will too!
So, I put together one pdf containing all 11 of these patterns. They're basically in the format I supplied to the publishing company: the patterns are abbreviated, but there is a hand-drawn chart for each one. There's also a legend included on page 2 to help you decipher the text and charts.
