Sorry for the delay,
I had to wait for the teething problems to be ironed out. Before I could reply with a picture.(all be it a naff one.)
The canopy straps are cast in a U shape (the two straps attached to the horizontal bar.)
There's not alot I can say about the folds in the canopy its just a few triangle shaped areas of clay on a box shape. I've no images of it in the raw so to speak. But there are some images floating around of the medival tents I did for 1st corps that show the method,(for want of a better word.)
Mark.
