Short story about people trapped in a cave, while time shifts around them

Question

This a short story about an unnamed pioneer/settler woman in charge of a group of people living in a cave. Time keeps shifting outside the cave, and they end up in different eras/epochs in history. She is also making some sort of tapestry(?) which she realises is a map or guide to where they'll end up next.

We thought this might have been a Stephen King story but couldn't find it. It was read in the last few years as part of an anthology (in paperback, pre e-readers), but unfortunately we've no idea when it might have been published.

Many thanks for any help.

Answer 1

Possibly Dame Anne McCaffrey's "A Flock of Geese"?

The cave was populated by random refugees, not an organized party. One woman ran the group; she would have preferred a permanent group who didn't challenge her authority, but so far it hadn't happened. Her greatest advantage was that she could sense when a time-shift was about to occur and could get back to safety. The cave was a safe place because it was in a place that hadn't changed geologically during human history.

It shows up in Moonsinger's Friends and The Girl Who Heard Dragons.

And it's a quilt that she's working on according to the Google Books excerpt that I've found.

There is a second linked story, included in The Girl Who Heard Dragons, "The Bones Do Lie".
