Two bundles of inking brushes for Krita 5 (I don't know if they work in previous versions, but it's free so just download the latest one
). Links are from the Krita Youtube channel in the description of the video posted here (I have edited the links to remove all the youtube redirect stuff, and just posted the direct url -
first link requires right click the link and save as to get the bundle file). To install the brushes go to the settings menu in Krita, open the manage resources window, then import resources the brushes should be imported.
