A Five Minutes Friday about making your own washes. No fancy thingies, just how I make my basic washes for terrains and other things. Demineralised water with 10% flow aid or flow improver. Matte medium, doesn't matter with brand. Acrylic its from Liquitex, Amsterdam, Pēbēo, Daler Rowney FW or what you like. Basic is a 50% matte medium with 50% water mixture in with you leave room for the additional ink for color. Shake well and test. Add color as much as you like, easy!
