Here you have a brush pack, that 15-6 years old me made out of various watercolour and pencil stains from my sketches. So, due to them being so old, I think they should work even with the PS 7.0. I just arranged them, cleaned up and over-saved the .abr file in PS CS5, but there's nothing, that shouldn't work in older versions I guess. They are simple, since I made them at the beggining of my digital painting adventure...
