This is a first try in braiding kangaroo leather. A basic 4 strand braid with a small keyring on one end and a loop on the other end. I think this could be useful for small camera wrist straps or finger straps.
The book I used for reference was Leather Factory-Braiding And Lacing For Fun. The descriptions are simple enough to follow but there aren’t many projects in there.
If you want a comprehensive look at the topic, you’re probably better off getting the Encyclopedia of Rawhide and Leather Braiding by Bruce Grant.
