oh would never iron every day...I just hang them up straight after washing. Thing with linen is that if you commute, they look all creased by the time you arrive anyway so it doesn't really matter if you iron or not in the first place.
Schools always far too hot imo. I have an image of you having to strip down every afternoon (ds's teacher has to do this as their classroom gets the sun - it is BAKING in there and she always ends up in just a T-shirt and trews by the time you pick up!)
