I was wondering, if you lined them with some transparentish gift paper (oh what's that stuff called?) would that prevent the rubbing against the bags?
You'd still be able to smell and see as well.
just happened to come accross this site: www.yourorganzabag.com
they have 25 colors and numerous sizes available. the 4 x 6 bags are $3.30 per 30-which is .11 each. i don't know if there is a minimum.
