Drawn with this week’s free GrutBrush, the “Humble Bee” natural media brush. It’s a thick saw-tooth edged opaque brush with a free flowing thick wet ink appearance, with a very slight width variation but when used with a lighter touch as I’ve done here it can have a bit of a crayonlike appearance. The background texture was created by scaling the brush to an absurdly large size. You can get the brush as always on the free brush of the week page
