A quick rundown: take your texture (probably find something online), make it grayscale, crop/resize to 512x512, save in the brushtext or papertext folder. The artist appears to use some texture as well such as in the leash, probably a custom made one but you can get a fairly similar effect just using the built in Paper texture, at least close enough to give you an idea of how to make your own.
You can modify it to be a bit more rounded as well, basically anything pure black will be converted into where the brush inks, so if you made put a thin oval instead, you should get something still elongated, but softer at the edges, which is probably how you can get the effect of some of the red/orange/pink flowers in the background.Īnd some spots appear to use the built in flat bristle (like the pink behind his arm). To get that flat brush style you can use a flat bristle, put it in elemap for sai 1, or bristle for sai 2.
