What were the old women doing?

If it is the scene that I think you're referring to, they were sitting in a group on rocking chairs, cutting yarn.

Explanation:

in Greek mythology, these women are the three Fates, named Clotho, Lachesis, and Atropos. In mythology, a thread represented someone's lifeline, and when the Fates cut your thread, it meant your life was over and you died.

In this specific scene, from The Lightning Thief, the Fates are seen cutting a blue piece of yarn, which makes Percy's friend Grover nervous because he believes they've just cut Percy's lifeline.
