Wait, this looks familiar... 

This will be a short video lesson - as the reversed lark’s head knot (abbreviated as RLH) is the exact same knot as the normal lark's head knot. The only difference is that it's seen from the other side. Hence the name, reversed.

To make the knot, instead of bringing your loop up the front of the dowel, bring it up from the back. Then down from the front and pull the cords through the loop.
