stisdale, I'm not Jan of course, but I'll tell you how I keep up with my yarn weights and fibers. (Sorry for hijacking your thread, Jan.)
I put them all on Ravelry, and reference where they are stored. I have labels on each drawer and box of yarn in my craft room. (Yarn Drawer A, Yarn Drawer B, Yarn Box 1, Yarn Box 2, etc.)
I just put the proper box name in the "stored in" blank on Ravelry.
Here's an example:
(of course, you have to sign into Ravelry
to see that link)
And I sort my yarn by fiber. Cotton, Wool, Acrylic, Wool-Blends, Baby Yarn, Novelty Yarn, Chenille Yarn, NICE yarn, etc.
I keep all my really nice yarns in a cedar box, to protect them. My other yarn is stored in plastic bins, plastic boxes, and paper storage boxes. I also have some yarn that I display in baskets, just to make the craft room look nice.
You can see my plastic bins (with drawers) at the back of this photo.
And here's a view of my plastic storage boxes. As you can see, I have some recent yarn purchases in bags that have not been stored yet. It's an ongoing thing, since I'm a yarn addict.
