I learned a super cool trick that is worthy of sharing. This is how you create a pattern and use it for different components. On a recent blog I installed and updated, I used a similar pattern to dress up the client’s blog because he wanted to match his existing business cards. No sweat. I used the pattern for the body background, the image background for the date, and then the background for the header because I didn’t like the sky blue I originally used. Here’s how I did it:
first set the background and foreground colors if you already know which colors you want to use. I’m going to use background #4b6ff7 and foreground #4b4640. Once the colors are set, hit CTRL+N to open a new document with both width and hieght each set at 4 px and the background set to Background Color. Select OK.
A little spec pops up with is a 16 px image of our background. Hit CTRL and the + sign nine times to make the image 1600%. and you’ll have an image like this:
Next step is to select the Pencil Tool from the tool menu. Select a 1 px brush, normal mode, and opacity to 80% in the settings menu at the top like this:

For this tutorial, you need a 1px brush, but you can toy around with mode and opacity all you like.
With the pencil tool selected, make a pattern you like. It will take you a while to get used to what the pattern will look like as a background pattern in full size, but you’ll figure it out in no time with a little trial and error. I’m using the following pattern:

If you’re happy with the final pattern, go to Edit > Define Pattern. Enter the pattern name you’d like to give it, I’m going to use samplebgpattern for mine as shown below:
Then open up a new file with a white background. I’m going to use an 800 x 200 header with a white background and fill it in with the new pattern. Once your image is open, create a new layer by going to Layer > New > Layer. You can name it whatever you like, I’m just going to use layer 1.
From here, select the paint bucket from the tool bar and set the options menu to “pattern” instead of foreground and then select the pattern you just made. There are a few preexisting patterns if you’ve never made one before. If you’ve made several in the past, you’ll know that the newest pattern you made is the furthest one at the bottom right. Here’s the menu settings you should have:

Click on the image to be filled and you’ll end up with something like this:

You can put text on it, insert images, do what ever you want. Enjoy.
