Origin of the Rosettes

The aprons as worn by Masons in the Grand Lodge of Alberta resemble those as given by the United Grand Lodge of England in the 1815 Constitution:

• Entered Apprentice: A plain white lamb skin 14 to 16 inches wide, 12 to 14 inches deep, square at bottom and without ornament; white strings.
• Fellow Craft: A plain white lambskin similar to the entered apprentice with the addition of two sky-blue rosettes at the bottom
• Master Mason: The same with sky blue lining & edging, 1½ inch deep, and a additional rosette on the flap.

The rosettes on the FC and MM aprons were not proscribed in England until 1815, and it appears that there original purpose was ornamental.
