How to extract patterns from PS

Adjust the size and DPI value of the original image to the size you need, and then select the magic wand and hold down the SHIFT key to select a little pattern. At this time, mosaic squares may appear due to magnification. Feather the selected area, and the selected range will be softer. Fill the area with a color opposite to the background color, fill it several times, copy it, and create it. The size is slightly larger, which is convenient to leave blank around the replication area.

I'm imagining the order in which I will do this, hehe, or do it over and over again. I imagine that the pattern you need is either too complicated, or the definition is limited, and the wand is not easy to choose. Let's start by adjusting the size of the original picture! ! !
