Nope, don't label, don't measure, don't mark. I sort mine by color (mostly) or some other hair -rained scheme.
When I get ready to start a new quilt, I browse through my books or magazines and pick a color line. Once I go through the bins with that color, one of three things will happen:
1. I find what I had in mind and there is enough to do the quilt. (rare event)
2. I find that I don't have enough of the fabric and find an unexpected alternative which, of course, requires a change in pattern. (regular event)
3. I decide to buy new fabric for the initial pattern choice. ( yeah, that's happened a time or two. lol)
