When ironing a kilt....
*I like to use a damp linen napkin as an ironing cloth.
*I make sure that I've laid the kilt out on the ironing board so that the pleats are exactly straight. (My kilt length in 22.5", I can fit it on the average ironing board)
*I press it in the same fashion as the previous gentlemen have stated before me.

Getting in a car whilst wearing a kilt.
* there are previous posts that dsicuss this.
* Driving in a kilt is oh so comfortable... but longer destinations, say over an hour... I'll get figity, it will get wrinkled a wee bit. I've observed at the Highland Games, gents who get out of the car in shorts and throw the kilt on over the shorts and then remove the shorts.
* Getting into a car whilst kilted.... I drive a KIA, not to hard... I had serious trouble getting into a Jeep liberty once (there was no step-up, there was no way to get into the automobile and control the pleats and be modest, I actually jumped up into the seat). Big automobiles with step-ups shouldn't be hard, like a SUV or something. If you are driving, the common way is to sweep with your left hand and hold on to the steering wheel with your right hand to guide youself into the car. If your good at it, you can re-sweep once you've sat down and are positioned straight in your seat. I think someone once suggested sitting on something like a tarp (I think), and just pivot yourself and the tarp.
*I suggest that some might not want to wear a kilt belt while getting in the car and driving. Test both, and many will probably agree with me. It's an easy thing to put on when you arrive at your destination.
