I didn’t get a chance to announce this week’s free GrutBrush on Monday due to my day job, but it’s been there and is still free until Sunday (24 hours left!) This one is a cross-hatching brush and I doodled this guy above using it. First I sketched the basic shape in black and then I ‘etched’ into it with the same brush, but using white to chip away at it (you could also use an eraser) and essentially carve into the black. Finally I made the layer a Multiply layer so that the white disappears and the paper background shows through.
As always you can get this on the free Photoshop brush of the week page
