Now that I look at it, I'm not so sure how "fall" a pinecone is. But whatever, no judgements here. We can do Winter a little early! This site is German, but is also translated into English. They have some fantastic patterns as well.
Updated March 22, 2012: I finished this little guy up last week and I think it is just adorable. It did not take very long to make, I just kept throwing it back into my project pile. I LOVE the way mine turned out short and fat though. So cute! I think I will be making more come this winter!
