I think... the horse could step in the cordeo, when the cordeo is right after his ears, and the head is very low... that is the reason I always 'braid it into her hair' IN that way... she must be very atheltic to be able to step in it.
Leather can break when a lot of pressure is used so it is not unbreakable... nontheless... if your horse steps in it and panics... I myself would like to have it break more easily.
My thought: just prevent the horse from stepping into it... act girly and make a little braid in the hair around one pice of the cordeo (don't know how to explain, will try to take pictures soon).
The only point I worked on was: 'where to put the buckle and where to put the ring' because I don't want the buckle to be lying on her manes, nor do I want the buckle to get all entangled with her manes. So that's a thing to think about.
Next one I'll make I'm thinking about adding two more rings, so that with longreining I can attach the reins to two seperate rings, and not one on the ring and one to the buckle... this works, but not like a charm
But... it's been a while I've been longreining, and even longer since longreining with the cordeo... such a shame
It's not hard to make one just try practice and see what comes out, and try again (got a fantastic bag filled with leather from a friend... so I'll see what I can make from that... starting with a new wallet. not horse related but still needed
