The last page of Sheryl Peterson's book “The Best Part of a Sauna” included great info about the sauna—the proper pronunciation, how Finnish immigrants used the sauna, different kinds, words like löyly, the cloud of steam produced by tossing water on the rocks, and vihta, the soft branches for swishing one's back, and directions on how-to.
She even mentioned the saunatonttu, a little elf, who warns people when a fire was getting too hot.
All in about 600 words. Neat skill.
