I need a birthday gift for my sis-in-law by Sunday. What are your favorite last minute gifts to knit?

I did a pair of cabled mug cozies. I'd look for the pattern for you but my computer is running super slow tonight. Just google mug cozy knitting pattern and a few will come up.

iPod and cell phone cozies are also fun and quick as is a quick clutch purse.

Did you check the stash busters sticky at the top?
