Easy peasy fabric scrap filing system...
2. I lay the fabric "scraps" out and place a backing board on top. I fold the fabric around the board, which gives it stability to keep tidy in a bastket. I secure it around the board with a straight pin.
4. I then file the fabric scraps into my baskets, which allows me to see what I have at a glance and keep things tidy :) The backing boards support the fabric, so it doesn't just pool up in the basket.
I hope this very simple filing system will help someone else...it is one of the best tips I have ever found.
