As the Harry Potter frenzy heats up this summer, how about some HP knitting? Patterns have been circulating for years, and there's the book Charmed Knits, which I have ordered because I foresee quite a bit of child knitting over the next few years.
I've also found this HP knitting community, where people post pics of their projects. Lots of folks are making scarves as seen in the Prisoner of Azkaban movie, using this pattern. The pattern designer, Lauren Kent, is also designing more intricate HP patterns for sale, including this yummy rendition of Hermione's cable-and-bobble hat from Prisoner of Azkaban.
I think if I were to make a scarf it would be in Ravenclaw colors. Maybe something else will tickle my fancy when Charmed Knits shows up.
