I really loathe making items longer than bracelets due to the amount of cord that has to be pulled through each weave. I have tried numerous methods to make the process easier. I discovered that doing multiple overhand loop knots on entire length of one strand is easiest, unless you have a better way. Which if you do, please share it. I have included pictures to help explain it better. Using the method I explain it cut my time making leashes in half. Picture 1 shows a basic cobra weave. The cord on the left side is left completely untangled off to the side. The cord on the right side is multiple overhand loop knots the entire length of the strand. Picture 2 shows an S across the top of the core for the item you are making. You will not be pulling any of the strand on the left through each weave. It is crossed in the S figure so you won't have to pull it through. Pull the overhand looped cord through the top of the second loop then under the core and through the bottom of the first loop and tighten it. Picture 3 shows the cord on the right passed through the S figure, leaving a loop on the right side. Pull the overhand looped cord under the core and through the final loop and tighten it. Picture 4 shows the finished weave. Just repeat the process the entire length of the item you are making. Each time you get close to a knot on the overhand loop knot strand, just untie it and keep going. If my photos and explanation are not good enough I will make a video to show what I am doing.
