Join the knot lines around the outside of the walls, so that there are no loose ends.

Pick a place where the lines criss-cross, and erase it so one passes over the other. Erase the other criss-crosses so that the over/unders alternate.

The Lover's Knot can also be made with rounded loops, which often looks nice, especially when you are using it for romantic purposes, like decorations, etc. It has a bit softer look to it, but it can be made either way.
