so if i understand right.............................
if you store your bags standing up the sides will sag over time
if you store your bags lying down the quilting will go flat over time
if you store your bags in boxes they cant breathe
if you store you bags in the dust bag they can get moldy
if you store your bags with the chain out it will leave marks on the bag
*sigh* did i miss anything???
Guess you just have to carry them at all times.

HA, you are a genius! I may have to use your idea.
