It's easier to buy yarn than finish projects!
I am in a phase where I can't stop buying yarn. I have a very large stash in my basement, and luckily, had stopped my habit a few years back (especially when I had kids and little time to knit). But this summer, I started buying all kinds of fun, novelty yarns to make scarves out of, and the habit has begun anew. I see all those wonderful colors and I'm swept away by ideas, some of which materialize and some which don't.
