Step 3: Product improvement, install a locking strap
So what you need is another short piece of nylon webbing and another two pieces of velcro. At this point I think I should point out that you should lightly burn the nylon ends where you cut them to keep it from unraveling.
Sew a piece of velcro to your new short piece of webbing. Then sew the other piece of velcro to the outside of the leg of the leash. At this point you need to sew the locking strap to the leash, it is hard to describe where so take a close look at the pictures on how this works.
Once it is all locked down it looks really good and that velcro is going to stay put through anything. I hope you enjoyed the instructable, as always stay tuned for more!
