What clear containers you already have scraps/material in set off to the side. Use an industrial marker to label contents. I see batting, fold, roll, and use sticky notes or scraps of paper to label type of batting and approx. size. If any empty cardboard boxes toss aside. Any quilted material like in the upper left corner on the pile, put that in a separate pile. You can use one of the empty cardboard boxes (if big enough) to throw your books and magazines in (mark it mags & books). Another thing mark the boxes so you can read it! You can start by making piles, 1 for novelty, containers for holidays, then separate colors. Don't just toss to this pile and that pile. Fold as you go. Also TAKE A BREAK! You don't have to do this all in one day, That would be nerve racking. Watching some of the YouTube videos may help on organization. You don't have to spend a lot of money on organization just be sure you are able to see what you have. A friend of mine uses shoebags to hang on her door. She keeps many of her quilting patterns in them. Any dresser drawers you don't use are good for what you don't use too often. Good luck!
