Why buy a leash from a store when it's so easy to make at home. Anyone can make one with just a few simple cheap supplies. You will need:
2 continuous yards of webbing
1 swivel clip
Plus either a needle and thread or if you have it a sewing machine to make it even easier. Although the sewing machine isn't really needed because there is very little sewing involved. This will make a standard 5 foot leash that you could find in any pet store.

Step 1: Step one
Ok now fold over one end of webbing long enough for your hand to fit in the loop. You want it to be loose on your hand so you'll be comfortable using it. Also be sure it is large enough for anyone walking you pet to hold it comfortably. Now tuck under a little piece so there are no raw edges and stitch in place. I did a square with an x in it to make sure it was nice and strong and went over it a couple times.
