Hats are a wonderful addition to any medieval costume.
Simple cap - available with or without brim, in wool or linen, shown here without brim. Other fabric options may be available, but lightweight fabrics such as cotton may increase the price because interfacing will need to be added to stiffen the fabric.
Truncated Cone hats, available plain or 'folded' style, with or without veil. Shown with folded style, and with full veil, in modern fabrics. Another style of veil which does not cover the face is also available.
This hat can be made with either heavy linen canvas, plastic canvas, or wicker/straw internal support, and can be made with any fabric.
