Step 4:
Now were going to define this as a pattern. Go to Edit - Define Pattern and click OK.
Step 5 - Final Step:
Finally, let's test out our new pattern. Open up any image that you like, and create a new layer. I will be using this
image for the example:

Select the Paint Bucket tool and change the fill from foreground to pattern. Select your pattern and add it onto
the new layer. If you like, you can also change the opacity and fill of the scanline. In the example shown below, I have kept
the opacity and fill at 100%.

You have just made your very own circle pattern!! Wasn't too hard was it?
