ALERT: Free brushes are NOT available to iOS or Android Mobile users.
Brushes are ONLY available on the SketchBook Pro Desktop and SketchBook Pro Windows 10.
Visit the Tips & Tricks page for free brush packs. However, before you do, there are some key points you should keep in mind:
If you are using the Windows 10 version of SketchBook Pro, you might be having issues with importing the free brushes. The .zip format is an issue when using the Microsoft Edge and Internet Explorer browser to download the free brushes. To correct this issue, use a different browser, such as Google Chrome. The zipped file will download correctly and you will have .skbrushes format files.
The zipped files can be imported into the Desktop version of SketchBook Pro.
Some of the brushes from older posts won't work on the Windows 10 version.
