I like the evert-fresh green plastic bags. We buy a lot of lettuce because we have house rabbits, and it really does keep better in those. I wash them a billion times. There is something in the lining that does it, but I probably defeat it because when I wash it, I turn it inside out ... use it, wash it, inside out, use it again - so half the time it's inside out, if that made any sense.
Other stuff, NO BAG. Nothing annoys me more (as a human) than seeing people put 2 fruits each in a dozen plastic bags. Are you afraid they will have sex? Are you afraid that the cashier can't tell the difference between the apples and oranges? Even if I buy 12 apples, it REALLY doesn't matter ... I just line them all up on the conveyor belt next to each other.
Oh - and don't even get me started on the sackers who put one thing in each bag. ugh. and then they want to double-bag it and tie a KNOT! like it is REALLY easier for me to carry 25 half-full plastic bags instead of 2 heavy ones?
I love the idea of lingerie bags - never thought of that! And, making them out of curtain fabric! Great!! I do most of my fruit & veggie shopping these days at co-ops and markets, so I get to "bag my own" produce the way I want it.
