First of all, thank you very much for the response!
I've been reading and re-reading it over and over trying to make some sense out of it. I should probably draw a picture to make sure I understood it correctly, but I will try without it first.
Did I understand you correctly that I would make a leash out of just a core. I will make a loop for the handle and then I would make a much smaller loop that goes through the ring on the snap bolt, then will start braiding over it?
that creates a whole new set of questions:
1) if the core has no end where and how would you start braiding?
2) this means that the braided loop that goes through the ring of the snap bolt is pretty large to allow braiding through. Is this correct?
3) I was looking at this website for a while. If you look at this page: http://www.leashesbydesign.com/Information/FAQ/FAQ.html "section 3 - how many strands do I need?", it says that all the leashes are done with the core, but if you look at the pictures of her leashes, the loops over the snap bolt are really small. so I really wonder what she does with the core, or does it mean that in her designs the core doesn't really provide the extra strength?
For that matter, now that I think of it, none of the leashes I've seen have that visible loop through the snap bolt, except the one posted by "KnotHead" on this forum, that has a very visible loop through the bolt, but he said he didn't used the core ( it's in this thread: http://leatherworker.net/forum/index.php?showtopic=38294)
Or maybe I just do not understand what you are suggesting.
