After searching forever for a crochet lighthouse pattern, I finally gave up the search. So far this is what I've come up with. It looks a little lumby in person, but that's just because I'm not used to stuffing things yet. Here's one of them. I made a black and white stripped one that looks nice, but didn't take a photo.
I posted the pattern on my site at http://crafttreasuresnj.com/crochetlighthouse.html
