Last November, I finished up a Humulus sweater. The result was ... fine. But it wasn't what I'd envisioned, dang it. Rather than live with minor disappointment (and because the sweater was purloined by the Elder Teen once I mentioned that I'd likely not wear it), I made myself one two sizes larger.
Yes, yes. I finished it just in time for summer, which is how most of my sweater knitting ends. But that's fine, really. I know winter will be around again -- and that Scott and I are on our way to Iceland in July, where the summer temps warrant some wooly goodness* in your suitcase just in case.
* Wooly Goodness would be a great drag name, imho.
