In keeping with the Dutch theme, here is another good tip that was submitted for the green genius contest. Therese has a great suggestion for putting off trips to the dry cleaners (even those green cleaners).
"This tip comes from Holland and works best in similar climates. Take sweaters etc. that are not stained but need to be freshened up a bit and hang them outside on a cloudy overcast day (damp and a bit chilly, but NOT raining). This is about as simple and as green as it gets."
