According to Sean M. Wright, writer and member of
The Baker Street Irregulars ("The Manor House Case"), who has constructed dozens of them, the deerstalker is most often made of cloth, often light or heavy wool
tweed, although deerstalkers made of
suede, white
cotton duck, and even fur or
denim are not unknown. "I even made one for the late Los Angeles attorney Robert Landon Kirste," said Sean, "who asked me to make a deerstalker of black velvet for formal occasions. When I asked if he wanted white ribbon to tie the earflaps, he demurred. 'I don't want to stand out,' he explained.” The cap is made of six (or eight) triangular panels with rounded sides, which are sewn together. If the sides of the panels are cut in a way giving them slightly rounded shoulders midway, the crown will become more squared and flatter rather than hemispherical. The cap may be deep or shallow, barely touching the tops of the ears, according to the whim of the hatter. Either way, it is usually lined with an inner cap of
satin, polished
cotton, or similar lining fabrics. Occasionally, one can find a deerstalker with a lightly quilted satin lining. The deerstalker's defining feature is a pair of semicircular
bills or visors worn in front and rear. The dual bills provide protection from the sun for the face and neck of the wearer during extended periods outdoors, such as for hunting or fishing. These are usually stiffened with
pasteboard,
cardboard, or layers of heavy
canvas. For a brief period during the 1970s, some deerstalkers were manufactured with bills stiffened by the steam-cooked and pressure-molded wood-fiber construct called
Masonite. The Masonite tended to crack and break into segments, and over time, was also apt to crumble at the corners. Along with its visors, a deerstalker often, though not essentially, has a pair of unstiffened cloth earflaps attached to either side of the cap. These are tied together by
grosgrain ribbons or by laces or, very occasionally, held together by snaps or a button. The earflaps, tied under the chin, provide protection in cold weather and high winds. They are otherwise tied together above the crown to keep them out of the way. Deerstalkers may be made of solid-coloured material, but they are most often found with
houndstooth check,
herringbone, or
plaid patterns in the
twill of a fabric that serves as
camouflage. Modern hunting clothes, including deerstalkers, are often made with either a red-and-black or an orange-and-black check pattern or tweed for both this purpose and
hunter safety, not least in actual
deer stalking, for which purpose
milliners originally constructed this type of cap. ==Variations==
