Textures are fun to use. In just a a magical way they change the whole feeling in an image. Most often, the image becomes softer and more romantic. I often have a texture on my photos, especially when I want to give a still life extra surface.
Below you can see the two textures I have used for my photo with the roses. I call them Bricks and Wall and both are photographed against house walls in a wonderfully warm summer Denmark some years ago.
Yes it is true, the surfaces of bricks, walls, wood and so on are great to create your own textures with. Not so difficult to create and fun to have your very own. Spend a day to search for them and then try them out on your photographs. I promise you will find them everywhere, just you start look for them.
Below you see the original image. A matter of taste, but I find that the top image is more appealing. However, it is of course how and in what context it will be used, what a feeling you want to give.
Anyway, this is a fun area to explore :)
