I knew I had a lot of yarn; shoot, I haven't seen the closet floor in months. The system of organization I had was "meh" at best--lots and lots of craft store bags with different types of yarn. So I bought a bin. A big bin. A 95 quart bin.
Ayup. That's about most of it. (Minus about 10 skeins, a bunch of odd balls, and 5-7 started projects.)
