This is probably the first time I’ve ever drawn the effect of a waterfall underwater. An unexpected challenge was on the left page, which is the back of one of the pages for last week’s linocut block print. Because the ink for that print was thick and dried to create a slight raised surface on top of the paper, the shading on the back of that page was starting to show the pattern of the print. It was like making a rubbing with a paper and crayon on top of an engraving. I solved the problem of shading that page without the print showing through by holding the page up at a corner and shading it in midair while being careful not to poke the pencil through it.
