Of course, the internet is my primary tool. Early on, I discovered that art and caricatures helped me visualize the past in a way that other available research wasn't doing.
In one drawing by caricaturist James Gillray, I saw a wig stand on the table behind the subject. I'd never thought about all those powdered wigs (mostly pre-Regency) needing a place to be stored.
Daily life of the lower classes often features in my novels, and the picture above gave me an inkling of what it could be like. A spinning wheel, carding tools to separate fibers, a churn, a kettle, and fireplace tools. Not to mention scarves and caps to keep the head warm.
Really not that much different than the stories of tools I'd heard of being used in my ancestors' past.
