The shoulder pad for the strap has a slightly different design that what I have done before. The strap will run in between the two layers of leather in its entire length. The thick piece of leather is cut to size and the thin piece is cut a bit oversize. The two pieces are glued together along the side.
After they have been glued together trim all around the edge. Scribe a line for stitching 3 mm from the edge stopping at each end so that the two end of the lines are 3,6 cm apart
Sew it together and burnish the edges:
The straps are made as usual. See here and here
The start of the holes start 6,5 cm from the end.
