1. Open Photoshop<br>
2. Create a new file with your desired size; make sure to note somewhere the dimension in pixels;<br>
for A3 size 300dpi, the dimensions are - W:3508px by H:4961px <br> <br>

'''Tip:''' You can also use the gradient tool to create beautiful grayscale designs.<br> Make sure you do that before applying the Offset Filter! <br>

6. To make the pattern completely centred, you should move the:<br>
- "horizontal pixels right" bar half the way of the original width (3508px / 2 = 1754px);<br>
- "vertical pixels down" bar half the way of the original height (4962px / 2 = 2481)<br>

<br>
7. Once the filter is applied, you can finish your pattern by adding elements in the formed empty space in the middle so it can achieve a seamless effect.<br>
