Leather is one of my favorite things to burn on, the hot tip burns into the surface like a hot knife in butter. It is really satisfying. However, its also a very dirty burn, it builds up soot on the tip quickly and requires frequent cleaning. I usually use an emery board or fine sand paper.
I started doing these ornaments or dangles because I had scrap left over from making large maps of Middle Earth. Every leather worker knows those scraps are way to precious to throw away.
These are available and can be personalized with your town or name if you like. They will also come with a jute or suede strap hanger.
