Kong Adjustable Fifi

Here I've rigged my Kong adjustable fifi with the slipperiest 6mm cord I could find. The colors should make it easy to spot amidst the tangle. Note that I've rigged the fifi to hook and unhook from the left, using my weak hand. In this configuration, the far end of the cord will be sticking either up or out, making it easy to grab to shorten the cord. On the harness end, I've tied a double-overhand knot on a loop. This will be used to attach the cord to the harness. On the far end of the cord, I've tied a double overhand knot to keep the hook from sliding off the end. Girth-hitched to the small hole is a piece of 3mm cord. The girth hitch is cinched tightly to the hook with an overhand knot, and makes the pull cord always stand proud. I've tied the end of the cord with a doubled figure of eight knot to make it easy to grab. Note that the grab loop is small enough not to be able to catch on the hook.
