I document my apparel fabrics so I know what I have on hand when I or one of my daughters needs new clothes. But my quilt fabric is another story. For one there is 5x more quilt fabric than apparel fabric. Two. I always buy three yards of every fabric I buy for a quilt unless it's a remnant. Then I just leave the tag on.
I do sort my fabrics by colors. So there is a box of blue and purple and one of red, orange, and yellow, etc. Then I have a box of what I call focus fabrics those with lots of different colors. that I use to pick the colors for a project. Sometimes the focus fabric goes in the quilt and other times it doesn't.
