If you are looking for a narrow strap to replace the chains that hold up your sporran, you need look no farther afield than your nearest harness maker. My local harness maker (one of the advantages of living in Mennonite country) made me a superior quality bridle leather strap (5/8 wide and 44 inches long) complete with brass buckle for the paltry sum of $20, including tax. The whole bespoke process took about half an hour, he did a decent job of matching the colour of the sporran, and chatted amiably the whole while.

The shop was a true time-warp, and going in was like stepping back a hundred years or so.

So. If you need a sporran strap look in your local yellow pages under "harness makers". You'll get something much better than the often usual rubbish coming out of China these days.
