I want to create this final output of image as in this answer, so first I need to create horizontal lines. I am very new to photoshop and a bit aware of Gimp. As I see every answer is in photoshop. Even the first question I have asked was on gimp which already has an answer for photoshop( my first question on graphics designing). So, I have decided to start with photoshop. But I am stuck at the first task itself :( Can someone help me with creating series of horizontal lines as in that answer. I tried according to this video, but ended up with below lines which has gaps between two lines instead of thickness of each line.
Here is what I currently have.
Can someone please tell me how to achieve thick horizontal lines pattern?
