Why does looking through a tiny hole make things focus?

When I forget my reading glasses and need to read small print I can curl up my forefinger (like making a fist, but only my forefinger) tight enough to leave only a tiny pinhole in the center of my curled finger. If I look through that tiny hole by putting the finger very close to my eye this makes the print come into focus.
Why? How does this work?
