Well Brus, I use the same method as you only I don't put the hanger through the belt loops. If you do, I would suggest that you clamp the hanger before it tops out on the loops to avoid the weight of the kilt being supported by the loops. I purchased my hangers from Stillwater Kilts.

Father Bill, I believe it is Steve who advocates using the plastic slack hangers. I think it is more a question of economics than of any preferred hanging dynamics, though I am confident it works just fine.

When traveling locally, I use the same kilt hangers that I do at home, and hang them on the hooks in the car and just like my jackets. For longer travel, I fold them aprons out and lay them in the top of my suitcase. I also always bring a travel steamer when going out of town.

And that's that!
