These are great patterns. Just make the garments shorter (waist length) to be Highland style...!

If you're going to portray a common "rank and file" highlander, as opposed to a "clan gentleman," you only need the second pattern, as a short sleeved waistcoat makes a great highlander's jacket.

BTW, I did Civil War for over 25 years. Plenty of time to reach the "burn-out" point...!
