1. Fold in the middle of each piece of fabric and overlap them on top of each other to make a couple of loops;
2. Grab the ends of the top (purple in our case) loop by reaching arm underneath the crook of the blue or bottom loop;
3. Take the ends of the top loop and pull them back through the crook of the bottom; lay them over the bottom crook;
4. Make sure the knot is in the middle by straightening and cinching;
5. Spread the ends of the top loop away from each other;
6. Grab the tails of the top ends by reaching between the top and under the bottom crook;
7. Pull the top ends back through the bottom loop and continue to pull through in order to lay them over the bottom;
8. Pull all of the 4 ends to cinch the knots tighter and shift to make them compact;
9. Make the knots uniform and nice looking by adjusting or twisting until you are comfortable with the result.
