Our red interior '61 Bel Air had a white fabric headliner that looked a bit like a basket weave print. We replaced it with something very similar that Ciadella was able to find. It wasn't exact....but very very close. One would need the original material to hold up against the new material to tell the difference. Sounds like you received the same stuff as I. It should work fine.
For the seats, we were lucky and Ciadella was able to find OE fabric for the cloth portion. They also had some reproduction material but the OE stuff had a richer look so we plunked down some extra money for what we thought was a more premium looking product. I don't know how well it will wear compared to the reproduction stuff so I guess time will tell. We are driving the heck out of the car so eventually stuff is going to wear out again. I guess that is the idea, right?
