i never did anything to my large biba with cream trim. It had the cream trim at the bottom and nothing ever happened to it. Still looks good even after selling it to my sister. I guess we should just take little steps like placing our purse on the back of a chair in a rest. instead of on the ground, or placing it in our lap etc... small things like that. My mom always told me to never leave my purse on the floor because it's bad luck [and i'll never have money] even when im at home, she said - always to place it on a counter or my dresser in my room but never on the floor.lol, we're also asian and there are many old wives tales... who knows if it's true or not.. hehe
