Clouds, Clouds, Clouds!
This is an extended set of clouds for use with Wonderdraft. They are made at 600×600 pixels. I have two sets: Clouds which is a base set if you want to shuffle through them, and Clouds2 if you want diagonal, vertical and branched clouds.
The zipped file contains the file structure that will allow you to copy/paste or drag-n-drop right into your Wonderdraft assets folder.
