Now for the tricky (to describe) part: Open the center section of the doubled twist, creating the two running lines, an intersection, an opening, the second intersection, and the remainder of the loop. While holding the bottom twist, pass the bottom of the loop up behind the whole mess, over the top, and feed it through the eye. Pull enough of the loop through to the size you want, and draw everything up.
To untie after the knot's been loaded, work the "ears" down the running lines a bit, then pull the loop back through.
