Most people probably know how to do this but I thought I'd write a quick thread about it. My 4 year old loves to go pick out the rope that we will use to come home and make our own leads. We usually go to Lowes and its pretty limited in color but they do have some nice looking rope from time to time. I'm sure there are other rope suppliers around depending on where you live. I like to use a 5/8" inch nylon or poly braided rope. Again it depends on preference. Then we go and pick out bull or bolt snaps (the hardware that clips the lead to the collar). There are a few styles and material to choose from (brass, stainless steel, zinc, ect. You'll also need rope clamps to reinforce the lead. Depending on what your hardware store carries there are higher quality rope clamps available but I do find the run of the mill ones are enough to enforce a heavy puller.
So you'll need:
rope
bull snap
2 rope clamps
hammer
insert the rope through the swivel on the bullsnap bring it through about 3 inches. Put the double rope into the rope clamp and hit it with the hammer until the rope is tightly fastened with it. The clamp ends should touch each other or almost touch each other.
Next is to make the handle. Decide how big of a handle you want and insert the rope clamp around the doubled rope (where the end of the rope meets, and handle should be fastened) do the same with closing the rope clamp, using the hammer until the rope is securely enforced.
Not sure how clear my directions are as its 2am and I can't sleep so I thought I'd do something constructive lol. There are some pics of the hardware you'll need. Total per lead is about 7 dollars and again it depends on what hardware and rope you choose.
Today we made a green/white lead. Now my little one wants to make a hot pink lead so that should be a challenge finding that color locally....we may have to pay Ellas leads a visit!
its not the most beautiful but it was my first one ever
