While watching wildlife today I grabbed a very green muskadine vine and peeled the bark off, which came off in very long strips. I proceeded to make an eight inch section of reverse wrap cordage with it as watched the woods around me come to life this morning. I went to pull it apart as I got up to leave, and was amazed that I could not break it between my thumbs and index fingers, even when wrapped! Grape vines do really well in East Texas even during drought (massive root systems), so this will be a good cordage source for me. I have never used green grape vine bark for cordage before, but this thin little piece has made me a believer!
