Textures are the “in” thing even in a world that looks so much at the new flat design concept — and the reason is not difficult to understand. The right texture can add interest, and make your slide content look crafted. If you cannot find the perfect texture, it’s best to leave your slide background unaltered. Texture and picture fills for slide backgrounds have so much in common. Yes, the same picture can be used for both a texture or a picture fill, but the results will differ. The main difference is that while a picture background results in your slide using a single picture as a backdrop, using a texture background can result in the same picture being tiled across the slide background.
