This I think is more suitable in beginners sanctuary but anyway,
You can make your own textures by using programs like Photoshop, Gimp, Illustrator, or even MS Paint. Gimp, and MS Paint are both free. Photoshop and Illustrator are a bit more pricey. Textures come in 3 sizes, 128x128 pixels, 256x256 pixels and 512x512 pixels. The bigger of these sizes, the more resolution they are, but they are more expensive toricredit wise.
