Hats receiving flat mounts fell into two general categories: simple unstructured hats in good condition and hats that would normally require a shaped mount but could not be mounted due to poor condition.
The standard for hats with embroidery or raised decoration is an e-flute tray containing a muslin-covered batting pillow. For undecorated hats, PhotoTex tissue could line the tray in place of the pillow.
This hat rests on a padded lifting board with a twill tape loop attached. A pillow covered with polyester stockinet sits inside the cap, and another pillow is placed between raised ribbon layers. The long ends of the ribbon are rolled onto tubes of acid-free paper and secured with twill tape.
