I was asked about where I got my long line in Riggs' picture thread, and since I made it I evidently need to post here.
I make one inch wide long lines, any length. They are flat nylon webbing, with a handle and clip at one end (so you can hold it, but it's also easy to hook the lines around things) and a clip on the other (for attaching to the dog. duh. )
They aren't pretty like Liz's but they work.
If people are interested I can sell them, what lengths would you want?
