French Lining
This lining is made from an oval piece of silk which corresponds to the
crown measurements. Measure the crown from front to back and from side
to side, adding one inch to these measurements. Fit a small wire to the
inside of the hat at the headsize and tie. Lap the edge of the silk over
the wire one-quarter of an inch. Gather the silk close to the wire using
a small running stitch. After completed, pin in place and slipstitch to
the crown. This lining will reduce the headsize of any hat somewhat, so
it should never be used if there is any danger of making the hat too
small for the head.
