Natural cordage part 1. Two strand twist with cattail. Ended up with about 12 feet. I didn't have anything 10 feet high to suspend this from, but I lifted it over half way on each side just to make sure it would lift it without breaking. It held just fine, and I'm confident it would hold more. I have learned a great deal during this lesson. It took me quite a bit of time to figure this out, but I've got a good handle on it now. I made up some nice 3 strand twist today, but forgot to splice in the eye! I'll have to go back again and do it over, but I'll get it done soon and make another post for that one. Thanks for an excellent lesson @Sgt. Mac!
