1. First, prepare white paper and marker, and write with a thicker pen. If you don't have a marker, you can draw a sketch with your signature, then write down your signature and take a photo with your mobile phone and import it into the computer.

2, open the PS (if not installed, download a simplified version of PS, two or three hundred megabytes), open the picture like a mobile phone signature. If the picture is in the opposite direction, select the menu bar above-Image-Image Rotation (just rotate to the right direction).

3. Select the magic wand tool and select "Add to Area" as the selection method. Make a selection and choose a signature.

4. Create a new blank layer.

5. Use Ctrl+c to copy the newly selected text, and click "Layer1"CTRL+V to paste. Then hide the background. To hide the background layer, just click on the small eyes next to it. So I saw the signature map with transparent background.

6. Hold down the Ctrl key and click "layer 1", which means that you have selected your signature layer. Then select Edit-Define Brush Preset in the menu bar, set a name, and click OK to finish.

7. Complete the renderings.
