Measure the length of the hammock using paces. When it's time to set up camp, just pace out the distance between a couple of trees and see if they are the right distance apart. For most people, five paces will be the minimum distance. 
If you have enough length in the suspension rope, wrap it around the support several times and finish it off with a half hitch around the support line. With 4-5 wraps around a tree with rough bark, there will be almost no tension on the hitch. It's fast and easy to do, and will be easy to untie in the morning.


Dress in loose, comfortable clothing so you can move about freely in your hammock.  
2. Set a cool drink and any other materials you might need next to the hammock before getting in.  
3. Back up to the hammock like you would to a chair.  
4. Pull the far side of the hammock up and above your head so that the bottom of it is at chest level.  
5. Lie back into the hammock.  
6. Draw in your feet and stretch into a comfortable position.  
7. Position your body so you lie diagonal in the hammock. This will support your back and provide the most comfort. If you're sleeping in an extra-wide or double hammock, lie across the center for extra support.  
8. Close your eyes and let yourself gently sway by pushing off from the ground.  
9. Move about as you normally would in a bed. The hammock's extra material on both sides will hold you in.  
10. Swing your legs over the side of the hammock and sit up when you wish to get out. Support yourself by holding on to the edges of the hammock.  


Hammocks may damage a tree. If your hammock will damage a tree, including the bark, it is illegal. When you tie your hammock, watch carefully: Is the tree big enough? Is the diameter of the tree at least 12" (38" in circumference)? If the tree bends because of your hammock find a larger tree or do not use the hammock

After you tie up the hammock, tie a rope in the trees about two feet above you. You can then hang things on the rope that you will need that will be within easy reach and you wont have to go searching for later (flash light, mosquito coil burner, light stick, etc.) My camping buddy hangs a fanny pack on it and uses it as a head rest. 

In addition to hanging things on it, if stormy weather rolls in, you can throw a tarp over the rope and hang out comfortably and dry while it rains (staking one end and tieing the other). Eureka makes a great nylon tarp about 6' x 8' that is lightweight and is perfect for this situation.
