A strange video that really serves no purpose except pure entertainment. Depending on your standards for entertainment. .... I made a really bad ink out of paper, and then drew with said ink with paper on paper. Why? I don't know.
ever see homemade watercolours/paints being made and they have to mull it into the vehicle. or maybe more like how sumi ink is made when you have it in block form. also maybe some things to try, homemade paint. could start with black. homemade acrylic ink? (shrugs)
