This pattern is for a net trimming on the crown for a wide brimmed hat.

From the pattern:
“A novel and attractive trimming for a wide rim hat is of Corticelli Crochet and Knitting Silk in variegated colors, black, blue, green, red, white, etc. The effect is of oriental lace net, which is draped over the crown and the ends finished of heavy tassels of the silk caught into jade rings. The hat is a light olive green soft straw and the rim is stenciled with a design to match the silk in color. The same trimming could be effectively used on a felt hat.”
