The knitting buzz is the sweater that the character Astrid worn on the show Frindge. It's red with buttons going down from the shoulder. Others what to know what the pattern is for the afghan that Olivia has in her house hanging over a chair. Non-knitter just want to know what the pattern is for the show.
It's very strange to non-knitters why we focus on these things. I once watch an episode of a TV show and was concentrating so hard on the pattern for two knitted hats that I couldn't tell anyone what the show was about.
I remember movies and TV shows that have someone knitting in them better than ones that don't. I thought that it was just because I'm obsessed with knitting but when I joined Ravelry I found out that I'm not the only one. There are a lot of us out there watching.
