Here's a little mockup of the handle splice that will hopefully help.
Next time you make one, could you take a pic of the splice where the tag end of the handle doubles back through the little starting loop? I made one last fall and looked all over for details on that splice but couldn't find anything. So I made mine as a shoulder sling with a king cobra stitch for the shoulder part.
I gave it as a Christmas gift to my cousin. I'll see if he can shoot me a picture of it to post.
Just tried making one of these , a lot easier than I thought it would be once I figured out the cobra weave. May go over the handle with another color to break it up a little. Thanks for the idea.
These are the type I make.
Attached is a PDF with directions.
Looks great! So how does the black "core" look inside the "connector" braid? You've got four cords entering from the handle side but two coming out at the leg-loop end.
