One of my most favorite sweaters - I call it the Spiderweb Sweater - is also one of the top ten patterns downloaded from Interweave Crochet. And now, it's in an e-book from Interweave.
You can also read a little about the sweater on the CrochetMe blog, by the editor of Interweave Crochet, Marcy Smith.
Here are 3 versions of the sweater that I made for myself. I have many more!
