Making welcome slogans with PS.

First, create a new text box with A3 paper range in PS (that is, the length of two A4s glued together), and then create a new layer with slogans. It is best to save it after setting the position. Then right-click the text box, select the canvas size, and change the width to A4. There is a 9-square box with 8 arrows pointing inside. Click the arrow in the middle of the left, and other arrows will point to it, then confirm and save the picture (print); Then the action returns to modifying the canvas size, and then modifying the canvas. Everything else remains the same. Click the middle one on the right of the 9 squares and confirm to save the picture (print). .......................................................................................................................
