Questions about single seam trews.

[figheadair]

I cannot help with the construction but in terms of the seam, the 'traditional single seam' is a military practice dating from the late 19th century and was always done using double-width cloth.

In practice, this style is essentially the standard late 19th century military cut in tartan. By contrast, the oldest pair of tartan trews I have seen have a double seam, as do many modern civilian pairs.
