Making a (first century AD) tunic

[Cheyenne]

I would say for basic kit, no. Unless you are prepared to cite references to any awkward questions from the public. The pictures are from grave goods, which meant the stitching is a decorative thing on high quality items. The decorative embroidery I refer to is mostly referenced from parade attire, which is very special occassions for example.

I would say use stitching that is the same colour and would then reflect the stitching on known examples.

It just stops you having to deal with crappy questions from smart alec plebs!!

These embroideries are from Late Roman attire too - so a good couple of hundred years after the plain tunics worn by the soldiery of the 1st/2nd century
