This is what I've made, as you can see.. pattern is not clear. How do I make the pattern clear like in the first picture.
- Make a background:
Duplicate twice and rasterize if necessary
On top layer, Transform Horizontal Skew 45° (Ctrl+T). Then Filter > Pixelate > Mosaic. Then Transform Horizontal Skew -45° effectively putting it back in original position.
On middle layer same thing but do -45° then Mosaic then +45°
Lower opacity of both layers to 50% and then move them to a position you like:
