We took a 10" x 17" piece of rawhide, and using a strip cutter we quickly cut the hide into 1/2" strips.
The strip cutter was invaluable to cut quickly and uniformly.
Wrinkles in the hide made us slow down, but not much.
Round and around, the hide quickly reduced to a pile of strip.
From that small piece, we cut a strip 21.5 feet long!
We soaked the dry rawhide strip in some rainwater and salt for about a half hour to make it easier to work.
It was easy work and went quick. Careful, though, because a couple of the 'wrinkles' in the strip broke easily.
It worked well to tie the pieces together and stretch it out - in fact after it dried we could hardly feel the bumps.
It has been really dry this December, so we didn't go out and restretch it.
After a week, we checked the cord, then worked it over a branch to make it more supple and smooth.
After the final workout, the total cord length had grown to almost 30 feet long!
Very cool. It is strong and easy to use. Fun!
