Now the lady not only wants us to have a stash -- but to take a test on it! Not going to happen in my world! Seriously I once considered this but I get more inspiration from"paw-ing"my fabric than from pictures. But I can scan fabric into 2 of my quilt programs -- so why not a fabric inventory. Even something as simple as a camera and jpegs into a spreadsheet might be useful to some. Myself, I use the stack by color and a bit of stack by theme (christmas etc.).
