There is a large variety of brushes available in Photoshop already, but it is still fun to create your own. Which brushes you use when creating artwork largely depends on the type of artwork you wish to create. For example, if you want your artwork to look futuristic you may choose smooth brushes with sharp edges. If you are creating a sketch on canvas artwork in Photoshop, you will probably want to use brushes that have more texture including uneven edges and voids in the middle. When you create a brush in Photoshop, you can design a brush that is uniquely yours. There are several different methods you can use to create a brush. Here is one of them.
Texture is an important element in a brush. There is texture all around to take inspiration from. Carpet, fur, and even an old sweater are some examples of places you can look to find texture. Take a pictures of texture whenever you find something that interests you to use for projects like making brushes. For this example I am going to use a picture I took of my back patio after my kids spilled sand all over it. Sometimes messes can have perks!
Select the Clone Stamp Tool.
Choose a clone brush that works best for the new brush you would like to create. I used the Chalk 23 Pixels brush and used the slider to change the Master Diameter to the largest size possible (2500px).
Select a portion of you image with the clone tool. Then open a new document with a white background. Paste your cloned image into the new document.
Desaturate your image to remove all color. Desaturate can be found under Images>Adjustments in the top menu bar.
Now select Curves by going to Images>Adjustments>Curves. The curves dialog box is used to adjust levels. I am going to add contrast to my image by darkening the dark areas of the picture so they contrast more with the lighters area. I do this by moving the dark point in the bottom left towards the center. You can also move the white dot in the top right to the center to adjust the light area of the image.
This is the result of adjusting curves.
Crop the image you created to remove extra space around it. Save your new brush by going to Edit>Define Brush Preset. A window will appear in which you can name your brush. Click OK. You have now added a new brush to your library.
Lets see how this brush appears for selection and how it looks in action.
As you can see by the number 1401 under the brush, this brush I created is HUGE! I could have resized the brush before saving it for easy use, but that is really unnecessary because any brush can be scaled up or down to any size by sliding the Master Diameter slider.
This texture is now ready for use on any project and in any color.
