Creating Paterns
Ok, to make your own patterns in photoshop, such as scan lines, follow these 3 easy steps.
1. Create a new document, about 3x3 pixels, and make sure it's transparent.
2. Take the color you want, and the pencil tool and make a design you want.
3. Now go to Edit > Define Pattern, and name your file whatever.
To use his pattern, go to your paintbucket, and on the toolbar at the top, change Forground to Pattern. Now select your pattern and your good to go!
Hope this helped out some beginers to Photoshop.
