Collar Of Brim
Cut the wire inside of the headsize wire in the center. Twist these
wires once and a half around the headsize wire, bringing the ends up at
right angles to the headsize wire. Join the second headsize wire to the
top of these wires, using the same method as for joining the edge wire.
This collar may be made very low or as high as the wires will permit. A
separate crown of wire is not always used in a hat covered with very
sheer material or sheer braid. In such a case the collar would be made
as high as possible to make a support for the crown trimming.
