Looks like my original pic post got as far as making the duct tape template. Once that was done, I cut the template along lines that I wanted to be seams, specifically up the back of the calf and up the front of the shin, as well as up the outside of the leg (where I planned to put all the straps and buckles). Note the triangular toe kick, to cover the laces:
I then used the template pieces to cut out a pattern using some leftover canvas. I neglected to get a photo of the canvas pattern pieces as I cut them out, but here they are stapled together for the pattern fitting, at which point I found that the pattern was somewhat too small. I cut out a new piece with several inches of additional fabric added on (the stripes at the edge of the pattern). The original outer leg piece is next to the assembled expanded pattern parts, with the straps stapled in place:
At this point, I went ahead and cut out the pieces in black leather (since the boots I planned to wear these over were black; I've since acquired a brown pair, and will probably make Version 2.0 out of brown leather):
That's where I was at when I worked on them in June.
