Hi everyone. I came upon this website while searching for an answer to my sleeper question. Love some of the stuff I see here and am looking forward to contributing. So here's my dilemma. I have a small collection of bags (15-20) that I use to keep in their respective sleepers and then shuffled them away. I ended up not using most of them because I forget they're there or can't be bothered to unstuff and remove them from their sleeper. I just moved into a new place with closet space containing shelves to line up my entire bag collection. I've removed all the bags from their sleepers and must say they look really purdy all line up. Even my hubby said 'hey, it looks like a boutique in there'. However, I'm worry that the bags will get dusty and deteriote faster, even though they're behind closed doors. Am I being overly protective of them or does keeping in their sleepers significant increase their 'shelf life'. They're in immaculate condition right now since they've been well protected (and many have never been used!) and I'd like to keep them that way. What do you think? Is no sleeper a big no no?
