Update;

The above advice worked like a charm!

I'd already hung both garents up when I got home wet, and by morning the creases were much less. It seems they were worse in the argylle, (an old Hugh McPherson)

Taking the above advice, I damped the worst creases a little more, but wound up ironing the few tough nuts, with the material covered with damp cloth.
result;
No creases where they shouldn't be!

The games in Canmore were very enjoyable....Fresh snow on the mountains!
Would like to have had a bash at sheaf tossing!...did plenty of that with bales, so in theory a sheaf should be a doddle!
Chucking a four-stone weight straight up above your head sounds and looks a bit neolithic still though. how they don't brain themselves always has me wondering...

Thanks again for ther combined advice, you saved mi bacon!
