Top half is scratched to direct the watercolour along these channels.
Attempted to burnish the bottom half of the paper to make it smooth but didn’t really alter the characteristics of the paper which still looks rough. But the flow pattern is different. This paper was also bulging down the centre. Worked well to apply the watercolour at the top of the bulge and the rest of the drawing just drew itself as it dried. My kind of drawing. 🙂
