Tying a clove hitch is an invaluably useful skill when lashing. It can be used for both starting and finishing a lash, making it extremely versatile.
Step 1: Loop Rope Around Object
The direction is not particularly important, just make sure you don't cross anything yet.
Step 2: Form X
You want to cross the ropes on top to form an X as shown in the picture.
Step 3: Finish Hitch
Loop the rope around one more time, this time feeding it underneath the X you made in the previous step. You have now successfully tied a clove hitch!
