Clothing and Costume
This evening, I worked on D&D economy recipes. I have fixed the ludicrous clothing weights by learning more about yarn thicknesses, and adjusting my terrible estimates for how thick average yarn is. My original wild guess was more than EIGHT times thicker than it should have been. Now the ordinary yarn recipes are set at a reasonable unit of 2250 feet per lb, with a thickness of 16 wraps per inch.
While learning about clothing design to adjust the square footage of cloth required for each item, I stumbled across the fascinating blog of Angela Clayton, a self-taught New York seamstress and costume designer who has made many historical and contemporary projects. The project which led me to her blog was her recreation of a dress based on a painting of a 15th-century Holy Roman Empress.
