The first/main thread (By Kestral and Kender) was good, with a few errors, the biggest being the crops thing. Greece, being both on the Mediterranean and so far south, plus the mountainous terrain to the north, does not experience snow during the winter, at least as a rule. This means that it's possible to grow crops through the winter, meaning that it might be possible to get as many as 3 harvests a year (Which they'll need as methods will be primitive, producing very low yields per man day). The other thing I had a problem with was that empowerment thing they started doing at the end, where was that coming from?
As for the spin offs, well cotton is a product of the industrial revolution, very early on but still. So clothes would be made out of stuff from that time period. Flax/linen comes close to cotton, but processing it is manpower intensive. Silk comes from China and isn't really an option. Wool is heavy and insulating, and also rather itchy, not something a girl from Tokyo wants to be wearing, especially near her privates. Hemp is pretty much the same, but more rough then itchy, with the problem that of you grow the wrong sort you'll get high just wearing your clothes. Which leaves leather. Properly cured it's only heavy and insulating, how Greece is a warm to hot environment which means you can't wear it over your whole body, so lots of skin will need to be uncovered, but at least modesty can be preserved.
