Creating series of horizontal lines in photoshop

Question

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?

Answer 1

Let's say you want a 2 pixel line and a 4 pixel gap.

1. Create a new image that is 1 pixel wide by 6 pixels in height, transparent background.
2. Take the pencil tool and set it to 1 pixel, this should be a square
3. Zoom in with Ctrl+Plus / Cmd+Plus until the grid appears
4. Pencil the very top with two 1 pixel points
5. You should now have 2 solid pixels followed by 4 pixels
6. Select All (Ctrl+A / Cmd+A) and then do Edit -> Define Pattern

Now open any photoshop image and you can select an area and do Edit -> Fill -> change setting to Use Pattern -> Choose your newly created pattern.

Answer 2

Create a horizontal line of your desired thickness.

Select the layer with your line and while holding down the alt or option key go to Edit -> Free Transform or use the shortcut command alt/option + cmd/ctrl + T. The use of the alt key simply tells Photoshop you want to duplicate the object along with transforming it.

You will see the transform controls appear. You should then move the horizontal line to a desired distance. Accept the changes by hitting enter or return

Photoshop then saves your Transformation in a neat process called Transform Again (in the Edit Menu). Note that you will have to hold down the alt/option key again to duplicate the result instead of just repeating the transformation. It is much easier to use the Shift + cmd/ctrl + alt/option + T to quickly duplicate multiple lines to your heart's content.
