Mine is wound on 3 sizes of comic boards and really large pieces are flat folded. I do not arrange anything according to color. I have several large wardrobe closets with shelves, and can stash my stash 2-3 deep. I can see all of it so I don't have to sort according to color. Do whatever works best for you. Everyone's stash is personal and it is good if you can see most if not all of it. Good luck.
