Roman Tunic - Help

[Martin Moser]

That the stripes on the toga were sewn on is from the book: H.R. Goette, Studien zu römischen Togadarstellungen (Mainz 1990) and it seemed plausible to me.

fair enough - that's one article that is on my "to read" list for quite a while now :-)
I don't necessarily agree with Goette on this one, but admit it is a possibility.

I'm no expert in the textile field, but as far as I know it would have been also impossible or at least very complicated to wave in a rounded border into a garment's rounded edge (wouldn't you end up with a zigzag pattern?).

You are right in the sense that e.g it also isn't possible to display a curve or a circle in a computer (i.e. zoom in enough and the pixels break down to a stepped or zigzag pattern). As long as the steps are small enough - read weave with fine/thin threads - it will look like a curve except is really looking close up.
