TUTORIAL: How to make a seamless repeating pattern ALSO: Good images for pattern making

You should be able to. If you take a picture with a camera, it is very difficult to get everything lined up straight and lighting all even. I'd recommend using a scanner if you have one. If the image is on a piece of paper, make sure it is completely flat in the scanner so it will go in straight. It won't always work, but is your best bet. Once the image is on your computer, go into CAP and select the "New Sticker" tool. Then, just find where you saved the image. Does that answer the question? Good luck!
