I couldn't find any for clip/manga studio so whipped up a super simple one. I figured people would enjoy this since it's that time of year.
instructions on how to import to the program:
save the sut. files, drag the brush files into your program into the brush area desired. You can drag them around to their appropriate subtools or tool area desired, now you can use immediately.
