What are the different types of aprons used in Freemasonry?

The Freemason's apron is fundamentally a plain white lambskin, symbolizing purity and innocence 1. In the symbolic degrees under the regulations of the United Grand Lodge of England, its design advances by degree: an Entered Apprentice wears a plain white lambskin without ornament; a Fellow Craft adds two sky-blue rosettes at the bottom; and a Master Mason's apron features sky-blue edging and lining, a third rosette on the flap, and silver tassels 1. Masters and Past Masters replace the three rosettes with three sets of perpendicular and horizontal lines forming right angles 1.

Officers and Grand Officers wear aprons distinguished by specific colors, emblems, and borders. Lodge officers may display their office emblems in silver or white 1. Grand Stewards wear aprons lined and edged in crimson, while Grand Officers wear garter-blue linings with gold ornamentation and their respective emblems of office 1. The Grand Master's apron is elaborate, featuring gold bullion fringe, embroidered pomegranates, lotus blossoms, ears of wheat, and a blazing sun at the center 1.

Jurisdictional customs vary widely. In the United States, aprons for the symbolic degrees are generally plain white lambskin without rosettes, distinguishing degrees by how the apron is worn rather than by decoration 1, though some jurisdictions permit a narrow blue border 1. Scottish private lodges may select their own colors and embellishments on a circular flap rather than a triangular one, while the Grand Lodge of Scotland uses thistle-green 1. In Ireland, brethren commonly wear simple cotton aprons edged with blue, reserving lambskin aprons for official festivals 1. Across continental Europe, aprons take diverse forms—ranging from shield-shaped to rounded—and feature varied border colors such as crimson or green, along with painted or embroidered symbolic emblems 1.
