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.
