This brush is very effective and can be used for many purposes like filling a text with stars, create a background with stars and so on.

If you don’t have GIMP yet, you can download it from here: GIMP

Step 1

Open GIMP, create a new file by going to File / New 500 x 500px.

Create a new Transparent Layer by going to Layer / New Layer / Transparency see fig 1.

Step 5

Right click on the Layer with star, select Alpha to Selection. Keeping the selection delete the layer with star as we do not need it any more, go to Layer / Delete Layer.

Step 6

Now we are going to convert the selection to path and back which will help us to avoid jagged edges of the star. Jagged edges become most visible when brush is used at small size.

Create a new Transparent Layer by going to Layer / New Layer / Transparency.

Go to Select / To path.

Now remove selection go to Select / None.

Next go to Select / From path.

Step 7

Take Bucket Tool, make sure your Foreground is set to Black and fill the selection.

Now remove selection go to Select / None.

Step 8

Take Scale Tool go to Tools / Transform Tools / Scale. Set Width: 50px, Height: 50px / Scale see fig 6.

Step 14

Now we are going to save the brush. If you are using GIMP 2.8 go to Edit / Copy, Edit / Paste as New Brush. Give a name to your brush, click OK.

If you are using an older version of GIMP, go to File / Save as / User / Gimp 2.6 / Brushes. Give a name to your brush, next select GIMP brush gbr for extension.

This is it, now you can use the brush.

Important notes:

Make sure to change Mode of the image back to RGB by going to Image / Mode / RGB.

If you are using an older version of GIMP, don’t forget to refresh your brushes!

A few tips on how to use such brush:

  1. To change colour of the brush, just set your desire colour as foreground.
  2. If you want to paint with gradient go to Tools Options and in Dynamics select Paint from gradient. Next click on the Dynamics Options and by clicking on Color Options select the gradient of your choice.
  3. Play with fade length, the bigger the number, the smoother the gradient will be.
  4. Also in Brushes tab you can change the spacing, the bigger the number the further will stars be one from another one.
