How do I get the Corkboard back?

I finally updated to 2.7 on my old Mac Mini (Snow Leopard) and now all my note cards are sitting on a painfully bright white background. How can I get the old corkboard background back? It was much easier on my eyes.

I’d like the lines back in my project notes, too while you’re at it please.

Thanks.

They both work fine for me. Have you tried these actions?

In Preferences:

Corkboard > Corkboard Background then select Corkboard pattern

Appearance > Notepad lines and tick In Document Notes
