After recently purchasing a couple of hammocks, I went back to look at purchasing some straps to assist with fastening to a tree. Was shocked that the strapping materials in a kit cost way more than the 2 hammocks I bought put together. So, I set in to make my own!
1st you need to find your local outdoors store that sells climbing ropes and strapping material. As you see in my materials list, I purchased some hollow strapping 1" width. It will be your judgement on the length you wish to purchase, but as I bought, 2ft is sufficient for each end, and enough to go around the back side of each tree to protect its bark and/or trunk from damage.
Hollow strapping material (2ft per end = 4ft Total)
Paracord (however much you need) I am using approximately 11-12ft as explained further in instructions.
Carabiner x 2 (durable to withstand weight limit; NOT the cheap $ store kind)
