I just started braiding kangaroo lace, and that is what I have been doing so far (using 2 strands, doubled over the snap to create 4). If I'm using a core, does it really matter if the kangaroo is braided in a small loop to go through the snap, vs just tying the core to the snap and doubling 2 strands of kangaroo through the leash snap?
Also, if you're braiding the whole length first without attaching it to the snap using 4 separate strands, how are you tying the core back to itself to create the loop for the snap and the big loop for the handle? If the core isn't tied back into the leash, I don't see how it would be providing any added strength?
