There are two ways to tie the figure eight loop. The first is to simply
take a bight of rope, surgical tubing, etc... and tie it the same as an
overhand loop, except with a extra wrap before passing the loop back through.

The second is to tie the figure eight as you have discribed. Then simply
rethread the end back into the knot following it in reverse leaving as
small or as large as loop as desired. This is how it would be used to rig
around a tree or anchor for abseiling or ascending using single rope
technique.

It's more difficult to describe how these are tied than to simply show a
person. But I hope you get the picture.
