Well, sort of. But it has to be believable. Which sounds weird, but if the world is not internally consistent, then the reader loses interest. One way to make a pre-industrial society of a fantasy world believable is to know how people used to do things way back when in our world. Actually there I have a head start over many younger writers. I saw my mother make soap/butter/cream/jam/ginger beer/ out of raw ingredients, or gut a chicken, or trim a lamp or darn the heel of a sock or cook over a wood fire. I saw my father skin a sheep, hang a gate, use a whetstone, milk a cow, build a house with only the simplest of tools and so on - all sights most Westerners never see any more.
When I moved to Asia there were other things to see or to learn: using a hand turned grindstone to make flour, winnowing rice, grating coconuts the traditional way, using a loom, weaving mats by hand, using leaves as plates and countless other ways of living with the natural and making do without the manufactured.
Titles: The Forgotten Arts: A Practical Guide to Traditional Skills (more about farming and building) and Forgotten Household Crafts (about cooking and housekeeping). The fascinating thing about both books is that he wrote about things he himself could do, or he went to people who still knew how to do these traditional arts and asked them.
I am going to continue this theme in my next post...and show you some more of the texts I am dipping into for my next books.
