Put them in their original dustbags, then put the covered bags gently into storage bins (don't pack them too tightly or they will mash up or get scuffed--a big no-no). For structured bags like the LV papillion, clean white or clear plastic trash bags work great to stuff inside them to keep their shape. The bins keep the dust and mold out. For extra insurance, a dehumidifier or the little DampRid jars work the best to keep unwanted moisture out and keep your precious purses from molding or getting damp! Plus, if you have to get out of your house/apartment quickly due to an evacuation (like for a hurricane) everything is packed and ready to go.
