New hobby, or new passion?

I think I might have to classify this as a new passion, right up there with knitting. Hand spun yarn is amazing. It's not something I can do every night, or something I can spend hours on, like knitting, but I am loving it.

It's relaxing, soothing, and the end results are beautiful. My hands begin to cramp after an hour, and my already bad knee isn't liking the movement of the peddle, but I'm considering spending a sizable amount of money on a wheel of my own, so I know this is a relationship that will be well worth the pain it may cause.

Dear Spinning,
I love you...
