It is not a brush to download, but a setting to draw for example a frame around an image

If not already opened go to Windows > Dockable Dialogs > Paint Dynamics, once opened, go at the bottom of that dialog and create a new dynamic



A new dialog opens, check the checkbox at the intersection of Fade and Angle, and give it a name (at the top), here I named it Rotative, we are done with dynamics



Select the brush tool and a brush in the Tool Options, for this example I selected the most common/used brush in GIMP and input those settings
1Brush: 2. Hardness 075
2Aspect Ratio: -14 (minus fourteen)
3Dynamics: Select "Rotative" (or the name you did gave)
4Extend the Dynamics Options to unveil the Fade length and Repeat and Inverse options
5Fade lenght: ~200,
6Repeat: Sawtooth wave,
7and check Inverse
Now you're good to go



One dab on the canvas, Ctrl+ Shift + click on the other side of the canvas for a straight line.

Result in just Ctrl+ Shift + 4 clicks after the first dab

Very cool
Thank you

Clever one Pix!

Post has been moved and also given a new name 'Brush Dynamics Tutorial for a Frame'.
Thanks for this tutorial. Don't know that anyone has done one on dynamics before?
It is now in the list and also in the newest tutorials list

Interesting!

Thanks again for this. Using this dynamic and stroking a path makes for an interesting finish. The only one I've used before was track direction.

Thanks every one for your kind words


Perfect! Indeed, it's much more a tuto than a brush, thank you Sallyanne
And also your title is way better IMO



I might have made one long ago to make some sort of "rope threads" > https://media.sciencephoto.com/h1/00/04 ... 0px-wm.jpg still with the "rotative" but 3 circles selection and a gradient inside each circle
But I can't recall if it was a "tuto" or just a participation to a thread in here

Just want to add some more positive and thankful words - well done, neat use of brush dynamics.

I did something similar a while back. Same method, but a different use.
