The clove hitch is best suited for tying around
something stable, i.e. a tree in your garden, or something like that…
Anyhow, the clove hitch is quickly bound, and fairly stable - as long as you do
not bind it around i.e an arm or a leg - the backside of the clove hitch is,
that it will keep getting tighter, if you pull the ends !
Another thing is, that it will need some kind of 'corner' or 'bend' to stay put.
This means that it's not a good idea to bind a clove hitch at the middle of a
diningtable - it will simply not stay there !
1/ Make a loop, having the longer end to your left-hand side, and the short end under the longer one.
2a/ Make one more loop exactly the same way.
2b/ Here I've changed the color of the loop you bound in no. 2a to let you see what happens to which loop.
3/ Now place the right-hand loop on top of the left-hand loop as shown.
4/ Put both loops over whatever it needs to be tied around ( here a red gizmo ), and pull the ends.
and this is what it looks like in the real world ( side view ).
