A Mitre is the traditional, ceremonial head-dress of bishops and abbots in both the Roman Catholic Church and the Anglican Church. It is also worn in Lutheran churches and Orthodox churches.
It is typically either decorated with trim or embroidered. It gets its shape from very stiff fabric or stiff interfacing. Using this Mitre pattern, you can make a Mitre out of either silk or vestment fabric.
In addition to the Mitre Pattern, you will also need one yard of vestment fabric, one yard of satin and one yard of very stiff material or a heavy interfacing. You will also need two yards of religious trim for the Mitre and lappets.
