For those of us who travel a lot, what do you do with your purses? I am especially referring to the security check lines...IMO the xray machine is really dirty cuz everyone's dirty luggage goes on it. But i can't just NOT carry my bags on trips!! Another problem is that i LOVE canvas and/or fabric bags, plus my favorite purse color is white or cream (i have a lot of light-colored bags in both leather and fabric) and i'm so obsessed with them staying clean what about on the airplane? Do you put your bags on the floor? Again, i'm just not comfortable putting a thousand-dollar bag where people usually put their feet!! am i too protective of my bags?
