I second Matt's voice on good materials. MY effort are strictly amateur in nature compared to his, or Wally, or Barb, or anyone who had done a lot of kilts. But I have made a living making hand made things for twenty years, and it matters not what you are making. The better the raw materials, the better the end product.

The one really nice tartan kilt I have made is better, because I had some practice by then, but also because the material is much nicer. Since seeing the work of real kilt makers, however, my efforts are limited to work wear kilts, and when I go out in the world I wear one made by someone else.
