Backdrop Designer - Setup 

Setting up: rrfreelance-po...
First create 2 folders on your desktop for example, 1 for custom brushes you import (these could also be images) and another for the images you save, you can potentially use your documents folder for your exported images.
What not to do:
Dont put folders in the same directory as the application, the automatically get moved.
Make folders outside of the application folder for the custom brushes and images. When backdrop designer starts it will ask where to place custom brushes, go into the folder you created (not within the application folder) and click save.
If you messed this part up, in the video you will see its easy to reset by removing the paths file in Backdrop designer appdata Local folder.
