I do not wear wool next to my skin as it wicks the natural skin oils so badly I would chronically have chaping. As I seldom perspire unless I am wearing synthetics, even with heavy work in the sumer heat, cotton next to my skin with wool works, silk works better. Synthetics do not generally breath very well so if I wear them I tend to become damp, even if I have been continuously cold. Same thing happens with ruberized wear.
I store fabrics in paper products. Either wrapped in paper inside a vacumn pouch in a rodent proof container or in cardboard boxes. I have had some materials, keepsake stuff stored for 20 years or more. It keeps rotating back into fashion and I don't change size. I never use moth balls, Yuck, I would be willing to try bay leaf, or wormwood, or rosemary or lavander. Or any handy combination of these.
And BTW, rodents will not go where there is neither water nor food.
