a fear that i have about my bags is that the handles are going to stretch out. normally i keep my bags just sitting on the closet floor, but recently i have so many that there is no longer room for that. i don't like stacking the bags either, so i am wondering if i buy some hooks and nail them into the wall, will the handles stretch out? i plan on keeping bags empty to make sure there is no extra weight pulling them down...but i am still scared to do this! does anyone know??
