Hose Pattern

While browsing through all the nice Extant Originals that I found on http://www.kostym.cz/Anglicky/obsah.htm I found a pattern adaptation that I'm going to at least include here hoping it will help things make sense. Here is a hose pattern from 14th - 15th century Germany.

[I suggest saving this pic to your own computer. It looks better on a white background than it does on my black.]
