Great replies, keep 'em coming. I'll comment a little later after digesting it all.

As mentioned in first post, solids would be a prime (if not the prime) product. My reasoning? Most of the current Irish Clans (associations, societies etc.) have decided on solid colour kilts.

Now, if I can get the College of Piping in Summerside to appoint me as their kiltmaker, I'd be set. . For kilts at their shop, they have them made in Scotland. I'll be signing up as a volunteer with them shortly, and will always wear a kilt when there. Free advertising.
