"5. The two things to avoid are Dreaded Shine which is caused (I think) by the surface of the wool glazing under the heat or the iron... Both of these can be avoided by:
– dampening the wool before ironing, and
– keeping your iron moving"

Someone instructed me also to always iron my kilt from the inside in order to keep the outside from attaining the "dreaded shine"...

In my experience, having ironed the wrong way several times before being told this, it takes a good bit of ironing a wool kilt to get a serious shine. But I think you'll find that unless you keep your kilt wadded up after it's been in the rain, most wrinkles fall out pretty easy...
