best way to model this?

Hi Im doing some work for someone regarding a mattress and im just thinking atm how to do different parts of the project. One of the aesthetic parts would be the pattern all over it (see pic)

Ive been having a think of how to do it, but can only really think of normal maps etc…and ideas how to model the mesh to achieve the rotated diamond effect you see in the image? Thanks

Add a plane
In Edit Mode subdivide it a bit

Go to Object Mode, add a Decimate modifier, set it to “Un-Sudivide” and give it only - 1 - iteration

Apply the modifier and go to Edit Mode :

MAGIC! well that was simple…

It was only the other day I was speaking to someone on this forum about whether or not you could undo sub surf! Thanks very much!
