Today's tutorial was supposed to go up yesterday. I had planned on writing it during my youngest son's nap. He decided napping was not on HIS schedule. Oh well. Here it is today.
What we'll be doing today is taking a hand-drawn image and creating a seamless repeating pattern in Photoshop. This can be done in Illustrator, too, with a slightly different method.
Small partial pattern drawing (I did mine using black pens & markers)
To begin with, I took a square piece of paper and drew a random patter in one quarter of it.
adaptation of a tutorial I read about a while ago. Find out how big your image is and divide it in half. My image, for instance, is 1756 px. Half of that is 878 px. You'll need that number in the Offset Filter.
Go to Filter > Other > Offset. Put the value for half your image (in my case, 878 px) in both the horizontal and vertical spots. The image you get will look something like the next image.
Now I want to blend all of these separate sections a little bit better. You can do a couple of things here. Print out your image and and draw in the white sections, then rescan and combine your images. You can cut & paste in Photoshop. Or draw directly in Photoshop. I chose to use Photoshop only.
To demonstrate how the pattern looks, I opened a Photoshop file of the doll and added the pattern. I selected the section I wanted to place the pattern, created a new layer, and set that layer to the Soft Light blending mode.
Open your image in Illustrator. Live Trace your image. Make sure to select Ignore White. Click Expand and then drag the whole image into your swatches panel. That's it!
This tutorial uses a few of the lesser know Photoshop features. Any questions, let me know. And there's a special doll to download on Friday!
