Apply a canvas texture to a digital painting with Krita

I wanted to make a digital painting appear to have a canvas texture, to make it look like any traditional paintings. In Krita, it is easy to apply a canvas texture over the digital paint layers.  In a nutshell, you just need to create an overlay paint layer with a tiled canvas texture image applied with some transparency applied. Or in more details, do the following:

Create a canvas texture paint layer

1. In Krita, open up a digital painting file that you want to create a canvas texture for.
   
   
   
   
2. In the Layers docker pane, click the + icon, as shown in the screenshot above.
   
   A new paint layer Paint Layer x is created. Where x is a running number.
   
   
3. Move the newly created paint layer above all the painted layers either dragging it above or you can use the arrow up/down icons. Name the layer as Canvas texture.
   
   

Select a canvas texture file

1. Click the Fill patterns icon in the tool bar.
   
   A drop down showing a grid of patterns appear.
   
   
   
   
2. Click on a pattern to use, e.g. 02_rough-canvas.png.
   
   
   

Apply the canvas

1. Make sure the Canvas texture layer is active. Then in the menu, select Edit | Fill with Pattern.
   
   
   
   
   The pattern is applied across the canvas texture layer.
   
   
   
2. Next, in the Layers docker pane, change the blend mode to Overlay.
   
   
3. Then, adjust the opacity to your satisfaction, e.g. 20%.
   
   The digital painting should look more like a traditional painting.
