One knot, two loops? Sounds familiar.
Thumb through the Double Loop section and the Fancy Knot
section of the Ashley Book of Knots for something that catches your
eye.
You can also retrace a Figure 8 (one end from each side) to make this
junction knot and it should look nice and isn't too tough to tie,
although it won't be a true Figure 8 Loop when you're done:

If you like a certain symmetric or nearly symmetric bend, you can
use almost any one you wish to accomplish your lanyard. Simply
encircle the middle of your line as if it's a passive object with the
two ends as you tie a bend. The middle portion should go straight
through the axis of the bend in question. An easy bend to practice
the concept on would be the Zeppelin Bend, as it is abundantly clear
where the middle of the line would pass (parallel to the arrows in the diagram):

get the hang of it.
P.S. Inserting foreign objects (including rope) in bends can change
their properties.
