In this video, we learn how to tie a plafond knot. First, make a loop with your string, then make a smaller one directly underneath it. Make a larger loop underneath this, followed by another small one. After this, grab the bottom and lift it to the middle of the one on top of it. Next, bring the top down and push it into the middle of the bottom loop. Bring the left hand side of string through the top of the loop, followed by the right hand side through the right hand side middle. Now, pull on the top and bottom until you have a square knot in the middle!
