Brother Loyd Caldwell, PM and Secretary of Dalton Lodge in Dalton, Georgia has for several years offered a unique visual aid for the "Winding Staircase Lecture" that appears in most US Fellow Craft rituals (Pennsylvania brethren will be asking "What winding staircase lecture?"). It is a 6' x 9' custom carpet with the proper visual cues for each step.
I haven't seen one in person, but the photo looks absolutely beautiful.

Which brings up another question. Is there a US or Canadian manufacturer of lodge carpets, with a checkered floor, a blazing star and tessellated border? The English companies have beautiful carpets, but the exchange rate and shipping makes them too expensive for most of to comfortably suggest to our lodges.
