Facings
A pleasing variety is sometimes obtained by using a colored underfacing
on a black hat. The entire facing may be of a contrasting color or
extend only from headsize wire to within an inch of the edge of the
brim. In this case there could be a strip of material the same as upper
facing an inch and a half wide finished at the edge of the brim with a
wire. Then the colored facing would be finished over the edge of this
with another wire.
