Thank you so much
travelerscloset! I treat most of my bags with Apple Garde rain and stain repellent. The only bags that I don't do this for are some light-colored bags as well some washed leather bags (Linea Pelle for example). I also condition the bags every now and then with Apple conditioner. Lastly, for some of my bags that are light-colored, with rolled handles, I will apply Lovin' My Bags For Handles Only to prevent darkening.
I currently store my bags in their dustbags inside large plastic bins. The boxier bags like MAMs, matties, etc. are stuffed with tissue. I just moved and haven't found a good spot for all my bags yet. Previously, I had them in dustbags on shelves inside my (overstuffed) closet.
HTH!
