I am making my own leather sporran strap. I am using a length of heavy harness leather and a Conway buckle to eliminate moving parts and sharp edges. I also plan to run the strap through the back of the sporran to eliminate the metal clips and D-rings altogether. My question (silly as it may sound to some) is not about the construction, but rather about how the strap is generally worn. Should the buckle be worn in the back, or should it be placed up front behind the sporran itself to conceal it, or perhaps positioned somewhere on the wearer's side to provide access for donning/doffing?
