I just recently wrote about a sock yarn competition that Berocco is holding. You can read about it HERE and click on the links. Perhaps they will be sharing some of the patterns that are submitted for the contest.
Another website you might want to check out for inspiration is Dawn Sparks' Fiddlesticks website. Click HERE. If you scroll through her site, you will find oodles of fabulous pieces she has done, a good deal of them granny squares but not your grandmother's granny squares! She does some of her stuff in fingering weight and it is just lovely.
