Today I realized I don't have a clue how to draw circles or squares in GIMP.
I knew how to do it in MS Paint, but Paint draws everything 1 pixel wide... I wanted thicker squares.
I opened GIMP but didn't have a clue how to draw squares... I could select squares but that was all.
So, I found this very nice video that shows how to do it. Here it is!
Have fun drawing circles...
