I used default brushes for the rough draft, but I’ll use my original brush for the final version.
You can download the original brushes used in this lesson from Clip Studio ASSETS.

A. Registering an image as a material
I start by creating a new canvas with 510px × 510px, 72 dpi, and gray basic expression color. Using the [Brush] tool > [India ink] > [Smooth] and [Rough] brushes, I draw a rough triangle in black.
I select the layer with the drawing and select [Edit] menu > [Register Image as Material]. I check the [Use for brush tip shape] option at the bottom-left of the dialog box.
I name the material “Triangle brush”, set the save location as [Image material] > [Brush], and click OK.
B. Creating a sub tool
I’ll start off with a sub tool that’s similar to the brush I want to make.
(1) I select [Brush] tool > [India ink] > [Bit husky].
(2) I open the sub tool palette menu by clicking the icon at the top-left, then select [Duplicate sub tool].
(3) I change the [Name] to “Triangle brush” and click OK.
(4) Now I have a new sub tool.
C. Setting the brush tip
(1) I select the “Triangle brush” sub tool and select [Window] > [Sub Tool Detail] to display the [Sub Tool Detail] palette.
(2) I select [Brush tip] > [Material].
(3) I click the ▼ button on the right side of the existing brush tip.
(4) On the displayed dialog box, I select the image material “Triangle brush” and click OK.
Now I’ve made my new tool, the “Triangle brush”.
D. Adjusting properties
I will adjust each property in the [Sub tool detail] palette. I set the [Texture] as “Dappled cloud 1" and turn on [Border of watercolor].
After I’ve adjusted the settings, I right-click the “Triangle brush” on the [Sub tool] palette to display the menu, and select [Register to initial settings].
Now my triangle brush is ready.
