How to create a custom Photoshop brush with the “Brush” tool
1. Start with a Photoshop canvas
You can really use any canvas size to get started creating custom brushes in Photoshop. However, for best results, I recommend working on a larger canvas. When you create custom brushes using a larger pixel size, the details tend to be more visible and stay intact when you resize the brush.
2. Make a new layer
In Layers, make a new layer without a background. This helps make selecting the new shape easier.
3. Draw or place an image
For custom Photoshop brushes, you can work with a file or drawing that has color, but the image will translate to black and white (wherein the black or color variation becomes the brush pattern).
For best results, play around with the contrast of the image to get a better idea of the results.
4. Select your object
Use the selection tool to select the object you want to use for the brush.
