Draw your pattern. The dotted line is the fold at the halfway point for the strap. Please note that the pattern below is not actual size. You will need to draw your own with those measurements if you have the same size strap (1 1/2″ x 27″) and same size lens cover (2 1/4″ diameter). Also, this strap cover is wider than the actual width of the strap to fit the pockets.
