When I first moved to my aparment, I practiced bass almost every day. Since I've started skating, my bass playing has become almost nonexistent. The money I was set to pour into bass lessons is being spent on league dues and skating lessons instead.
That could be another reason for my knitting resurgence: it doesn't cost me anything. Aside from the yarn I bought to make the sayonara sushi scarf and some beautiful impulse sock yarn, everything I'm working on has been made from yarn already in my stash using needles already in my arsenal.
And there's no end in site to the leftover yarn: last summer my friend had a stashbusting party (which I've mentioned but never ended up writing about in depth), her sole purpose being to get rid of as much as she could so she had an excuse to buy more yarn. Any time I mention using leftover Simply Soft or Microspun, that's where it came from.
