You know browsing around sites is also something I will do when I have a case of the creative blahs that doesn't resolve on its own fairly quickly.
I like to peruse Ravelry and admire the amazing work there reminding myself that I , too, will one day knit a Starmore Sweater.
(The most difficult part won't be gathering the courage to steek. That actually kind of excites me. It's the shelling out of major cash to get one of her books that is the scary part.)
I like to go to Knitty and look at some of their patterns that I maybe didn't pay attention to the first time around. Then I like to dig into the archives and read or reread articles on technique.
When I am ready to look at all patterns, all the time, I go to my big 3:
Before, I'd peruse them, thinking about which ones I might like to make and with which yarn I had in my stash. Lately, though, I have also been looking at some sweaters that I might have passed by before and pondering how I might steal some element or rework the design to turn it into something I might like.
So maybe doing something like that might help too.
