Could you say what is the story describing aliens that have giant canvases for travaling in the space using solar wind? People hunt them for their costly canvases. And in some point of time it is found out that they are rational beings.
I believe it is a Ray Bradbury story.
Any thoughts are appreciated.

Sounds like Raft by Stephen Baxter.
