The kicker? If the paper bag is made well (not the rice paper thin re-re-re-cycled stuff), people tend to hold on to them for re-use anyway. I do....They make excellent masks for airbrushing.
Oh I love the paper bags! They have handles and yes, I save them also. They make wonderful trash bags. Only thing that gets my dander up is they no longer double bag for heavy items like they use to do in the good ole days!
