I ruler fold my larger pieces, my FQ I am like tartan and fold them square , I store these on edge in a small plastic bin, all my smaller scraps
That I would use for applique I iron them and fold them so they are tidy and these are stored in a cupboard by colour, don't iron them after you have folded them, I am a scrap quilter, so there fore I have shoe box's for different width strips, same for charm squares. I also have boxes for seasonal fabric, and children's fabric. Hope this is of some help to you
Happy quilting
