But an author who wants her historical novel to be taken seriously works hard to avoid such things.
It’s important to remember that before the Industrial Revolution almost everything was handmade. This meant it took a long time and was therefore expensive. On a winter’s night the family sat in one room, in front of the fire. When you have to gather and chop the wood yourself, you aren’t going to waste it heating several rooms. The men carved furniture or household implements, the women spun wool, carded it and wove it into clothing.
If you didn’t grow it or make it yourself, you needed to sell your crops or your labor to get money to buy whatever you needed. Which translates as, poor people didn’t have them!

If your book is set in America, maybe they should play tennis instead.
