Mike, I'd be glad to, but mine are very simple when done for areas of limited view.
Try it, it's not difficult. Cut the strips of paper against a straight edge, then cut to length, making them longer than required.
I cut the 'buckle' ends to a point, and then pierce the center with a compass point held in a pin vise, to create the impression of a buckle. The strips are then painted the desired colour and allowed to dry, which is quick on paper, and the 'buckle' is then painted a dull silver.
Adjusting buckles are drawn in with a propelling pencil, sharpened to a chisel edge, as is any other detail, such as end stitching or cross retaining bands.
If desired, an extra piece of paper 'strap' can be added to the shoulder straps, to represent the 'free' end of the adjuster.
The straps are then positioned over the seat (or through the seat slot on some types), and adjusted to allow for the 'drape' and positioning of the fastening buckles. The ends of the straps are then glued, at the rear, with a spot of CA, and any excess chopped off with a scalpel.
With the desired 'drape' achieved, a tiny spot of CA is applied under the fastening buckle, and this is then pressed into place on the seat base.
This is repeated for the lap straps and, if for Luftwaffe, a further piece of wider, angled paper is added, beneath each strap, to represent the pads, and painted a darker brown.
Doesn't take too long and, as longer lengths of paper have been cut, if you mess up, it's easy to start on a new strap.
I've been doing it this way for fifty years or more,although in larger scales, if aftermarket fabric straps aren't used, I use a fine fabric and ass more detail using wire, plastic rod and strip etc.
