I have been using Paint.net as my primary PC based design canvas for about 7 years now.
Now that I have a fairly decent following and am commercially selling some of my designs I thought I would show y'all some of my work.
The latest design I just finished yesterday is the Rev 6.
Bill Compeau-Ark Instruments, Windsor Ontario
