Went to a living history event at Fort King George last weekend. (Evidently, they get a little irate when called reenactors so I try not to.)
The blacksmiths were there, demonstrating their craft. The weather was over ninety degrees, no shade except for the huts around the fort perimeter, and a wood fire where they worked.
Looks like they may have been wearing linen clothes but the soldiers had on wool uniforms as per conventions of the era. Glad I wasn't around then!
Got to admire these people, even if they only wear the clothes and work the trades for a few hours/days!
