Create a New Image, and set the following Width and Height and Fill with attributes. Alternatively, select Width and Height dimensions of your choice.
If you are not printing your work, set a Resolution of 72.000 Pixels. If you are printing your work, a resolution of 300.000 Pixels will be better.
Now, right-click over the Background Layer - and from the subsequent drop-down list click Add Alpha Channel.
Then from the top menu, choose Filters then choose Alpha To Logo and then choose Blended. And from the subsequent Script-Fu Blended dialogue box, enter settings of your choice, and then click OK.
To finish, from the top menu, choose Image and then choose Flatten Image.
Congratulations, your Blended Texture is complete, and is ready to Optimise and Save.
