Thank you for your very helpful replies.

How does one go about commissioning kilts from Barbera Tewksbury? A Google search finds many links to her book, but not much in the way of information on ordering her kilts.

On sporrans and accessories, is it safe to say that most of the highly-regarded U.S.-based retailers contract the manufacture of these items? I'm interested in items produced by third parties so long as they're high quality and unique.

I understand what you mean about some U.S. sporran makers not following traditional patterns or aesthetics. I recently attended the Maryland Renaissance Festival with my family, and all the items marketed as sporrans were either nontraditional or very rudimentary. I also noticed that many attendees wearing kilts chose to incorporate a lot of nontraditional items into their outfits.

Thanks for the J. Higgins recommendation. I'll take a look.
