So, I have downloaded a bunch of brushed from Deviantart and a few more on tumblr.
I honestly forgotten from where I downloaded this all. please forgive my short term memory whoever you are
I honestly didn't even tried
everything and didn't even use a great percent of it all.
The brushes have more .png files and some .bmp (I didn't use bmp, so I didn't try any of them). Feel free to download it.
(Note. Because my drive space is limited, I might deleted some brushes I deemed useless in the future and replace them and deleted the .bmp altogether. So if you want to, just download everything first)
I only ever tried them on medibang mobile (since that was my only tool, really :v ), do if you have problems with the settings, post it below.
And it would be great if any of you that have free brushes could shares them too. (I prefer .png file. ;3 )
