I'm not sure on the question about clothing. He might try doing a Google search for Colonial Woemn's Clothing. There's a book by Beth Gilgun, that I can't seem to recall right now, but she covers just about everything for women's clothing from this time period. I think it might be "Tidings of the 18th century".

One person who knows what she is making, is Michelle (last name unknown), who owns Sew It Seams in Colorado. I can't seem to find her web site right now though. Another one is www.bakertownsutlers.com. Check the Links at the Historical Trekking site, too. There should be something he's looking for.
