Here I am going to show you today a tool in gimp that I didn't know how it worked, but now I do so I will show it to you here.
First you have to be in the layer you want to edit and then you have to click filters. Next go to render and inside render click gfig:
After you have clicked here it is going to open a small window with a white background and you can draw whatever you want but don't forgot that this is only for geometric figures.
I hope you like it <3 p="">3>
