G.N.
The way I was taught and still to this day Its how I tie my sneakers/shoes. Take the 2 strings tie them like you normally do, then take one string fold it in half making a bunny ear and do the same thing with the other one, then say the bunnies are gonna run around the tree and bring them together and putting one under the other and pull them together.
Hope that makes sense. Hard to explain without showing.
