Hi Ron!
I'm with Seuss and Raindog here. I know diddley squat about sewing leather, but I find this thread (pun intended) to be fascinating.
I also love looking at these classic Moore and Heiser sheaths, not to mention the Randalls that go with them.
I'm not stringing you along either.
Remember folks: "A stitch in time saves nine"...
Cheers!
David
