When using the brush tool, what's the best way to 'fill' and sketch style image in adobe illustrator?
A simple example would be a triangle that is sketched with the brush tool trying to create a more stylised look then just using a shape e.g so slightly jagged edges. In an instance where this sketch doesn't form a complete shape how would you go about filling in this path? I've thought of a couple of approaches but not sure if they're correct. I'm trying to create some sketches but the overall goal is they can't be fully transparent, even if they are just black and white but I also don't want a fully filled in background.
Use the background colour of the image to create a join that does fill the path.
Create a rough shape path using the pen tool under the sketch a filling this the desired colour.
what's the usual workflow for this?
The other issue is that this is being imported from Adobe Draw, so the path, is a set of different brush strokes to being with. Here's a contrived example of a stick man face. The idea being the face is a flesh color, the eye and different color and then the square box would represent the document where the background should be plain. I know in reality a stick figure could be drawn using shapes, but the real image is a trace of a sketch where the style has the incomplete lines.
