Section 1: Create Trendy Lines.

Let's create trendy lines for the poster. To create the lines we have to use the adobe illustrator. So be sure  that you should install adobe illustrator. Then open up your adobe illustrator and then create a new document or simply press CTRL+N from your keyboard. Then select profile Print and select A4 size. Then leave all the settings as it is. Then hit enter or click on OK. Then go to the resource files and open up the swatches image. And drag it into photoshop. And then select rectangle tool and make 4 boxes. Then select color picker to pick up every color from the image and fill every rectangle from that color. And then select the pen tool and make the shapes as I have created in the video. I have used the pen tool and line segment tool to create the shapes. Then to make rounded edges of the rounded shapes go to Effects then select the stylize and then select rounded edges from there. And adjust the roundness of the shape which you want. See the video which value of roundness I have used. Then open up your brushes window. If you can't see the brushes window from your right panel. Then go to window and select the brushes. Then select those boxes which you have created. Then click on new brush icon and make a new art brush. See the video to learn how to create brush. Then select each shape which you have created with pen and line segment tool. And apply that brush on those all shapes. And then adjust the stroke of that shape according to your need. As I did in the video.
