Today we are going to use PhotoShop to create a seamless tile. To begin with, download one of the images below [or use your own]. Open the image in PhotoShop.
Choose FILTER > OTHER > OFFSET > enter a horizontal and vertical number (i.e. 100)
Use your clone stamp tool, soft brushes, etc. and smooth out any hard edges or obvious spots which will make the tile more obvious. Save the image and test your tiled image as a web page background or as your system desktop.
