"Bed" Bonnets were/are worn to keep body heat from escaping during sleep. The examples shown are in muslin.
"Soft Bonnets" I've used many types of fabrics with this style. Muslins, Velvets and even Suede!
Elizabethan - Tudor Style Coif I began making these as a fitted hat, but, after many requests, changed the design to something adjustable. Both are available. With or without an oblong shaped "Bongrace".
The Tudor period usually refers to the period between 1485 and 1603, specifically in relation to the history of England. This includes the period in which Henry VII ruled (1457 - 1509), and also includes the Elizabethan era, which is the period associated with Queen Elizabeth I's reign (1558 - 1603), considered to be the "Golden Age" in English history. During this period, as today, styles of coifs varied.
