Decorating Bonnets by Kimberly Lynch Saturday, April 28, 10am-4pm. Cost: $35, materials extra. Learn to decorate a bonnet in the latest fashion of the late 1850- early1860's. You will need to bring either a silk drawn bonnet- completed or a straw bonnet form - finished. You will also need a variety of trims such as silk or paper flowers, cotton lace, silk ribbon. Antique ribbon and lace work very nicely. 1 1/2- 2 yards of wide (2 1/2" - 3") ribbon for bonnet ties. If you are working with a straw bonnet, you will need 1/3- 1/2 yd of silk for the curtain. General sewing supplies such as hand needles, thread, pins, scissors, wire cutters or needle-nose pliers,
