I don't have anything to add regarding how to store your stash, but I do have an observation. Your photo shows some of your fabric very close to a window. If you leave it there very long before using it, I would be concerned about fade marks developing. Something to consider if you are not the type to rapidly use your fabric. This is something I had to consider when choosing my method of storage, as I will keep some fabric for years before I find the perfect use for it.
