Figure Eight knot is tied almost identically to an overhand knot, except you "turn left" instead of "turning right" into the loop. Under no circumstances is a figure eight knot harder to tie than an overhand knot.

In fact, I've practiced the figure 8 knot so much, that it takes more effort for me to do an overhand knot these days. Figure 8 is really easy.

Just as the "Granny Knot" is a mistaken square knot / reef knot... the "Overhand Knot" is basically a mistaken figure-8 knot. Just turn the other way, and the knot will be far, far stronger.
