I have a healthy stash with some pieces dating back decades. I LOVE my stash - it gives me great joy. When I get persnickety, my DH sends me to my room to "pet my stash" because that always puts me in a good mood. All but the scraps are stored in cabinets. Living in the country and dealing with all the dust, I keep my fabric behind closed doors. Scraps are kept in plastic bins. The most important part is keeping fabric away from sunlight.
