Another super historical hat pattern from Lynn McMasters.
This Bonnet is just two pieces, the back and side. The pattern piece for
the side can be cut on alternate lines to give a bonnet that is earlier
or later within this 20 year span. It includes instructions for making
it as a fabric covered hat or making it up as "straw braid”.
