Mary Atwater included a snowflake twill in a Shuttle Craft Bulletin (August
1945). The draft appears to have been done from a fabric analysis which left the
first few threads a straight draw and the rest of the threads in a satin type
order. When the shafts and treadles are rearranged, an advancing twill pops up
and this makes for easier threading and treadling. An advancing twill section
with a reverse in the center is the main feature of snowflake twills. Other
types of twill threadings are added to the draft – such as points and satins.
This is the basic snowflake twill.
