I'm like Crycket, I play World of Warcraft or the Sims 2. Though I also play them while I'm in knitting mode, so they just might help keep me from getting "burned out" on knitting in the first place. I also read, as there isn't anything like getting immersed in a good book!
If I'm just feeling uninspired, I will looking through the recently added patterns on Ravelry, FO threads in the groups I'm in there or just cruise patterns period.
For my summer knitting, I'm hoping to get good at socks and maybe knit a couple market bags that I have queued.
