To answer a few questions that have come up -- yes, I'll gladly make a solid color, and it doesn't have to be a tweed. Most mills offer some solid color options in either 13 oz or 16 oz. I've done saffron before, for instance. So talk to me about what kind of color you want and I'll see what's available for you.

Which brings up the second question, which weight is best. Hands down, the 16 oz heavy weight is my preferred cloth for a 4 yard box pleated kilt. I use it whenever available. I will also use a medium 13 oz weight, if that is all that is available. It does fine, but not quite as well as 16 oz. I really wouldn't use anything lighter than 13 oz at all.
