Use about 10 inches of 3/4 inch ribbon to make the "tie". I'm using two toned ribbon to make it easier for you to see how to do it. The brown is on the front, the pink the back. Hold the ribbon, right side up in your left hand with about two inches sticking out on the back. You will use this back 2 inches to tie the knot.

Now take that two inches and wrap it over the top of the ribbon, going from the right to the left.
