In Scottish Lodges the aprons of an EA are plain white, those of a FC have two rosettes, those of a MM three rosettes, forming a triangle. Most MMs buy a 'dress' apron which, in addition to the rosettes, is edged with a wide ribbon in the lodge colours. These colours are chosen by the lodge at the time of its erection (founding) and may even be tartans. Many aprons have the rosette on the flap replaced with a S&C. Past Masters may have the rosettes replaced with 'levels', with a 'Past Master's' emblem on the flap. The lodge supplies aprons for all office-bearers which have the jewel of their office on the flap.
The aprons of my lodge are edged with royal blue, identical to the edging found on the Grand Lodge aprons of the UGLE. Our Grand Lodge, Provincial Grand Lodge and District Grand Lodge aprons are edged with 'thistle green' .
Meetings here, with members and visitors from both Scottish lodge and those of our sister jurisdiction, the GL of Newfoundland and Labrador, with their English-style aprons, plus, at Installations in particular, Delegations from their Grand Lodge and our District Grand Lodge, can be quite 'colourful'!
