What you need is not a grain mill, but an olive press. Of course it would be hard to get the oil stains out afterwards, but you could definitely get a good crease in those underpants. That would have the additional advantage of being drivable by donkey-power, so you could iron on a windless day.
In the tradition of this place, may I announce that I am going to the Derbyshire County Show on Sunday - usually good fun and only 30 minutes' walk away. Tickets already bought, so let's hope the weather holds.
I am doing the usual this weekend; to the mill tomorrow morning, hanging about, drinking coffee, but remarkably there's no laundry to do as I made a sustained affort during the week to get it all out of the way. I have even stowed away the washing line. On Sunday, I'd like to go for a bike ride [destinatioin: ice cream] but it's a bit weather dependent.
