I'm surprised how often BTS artists come up with clever ideas to enhance their artwork. Lisa Hjorth confronted the challenge of creating tiny little bird feathers (you know, the ones that cris cross on their backs) with an unlikely tool- an eyelash comb. (@Tweezerman from @Ulta)
Lisa drew in a layer of yellow first and then embossed it down with a cris cross motion of this tool. Then she layered in a Veithin black over the top, which just "skipped" right over the yellow color below. Very resourceful, Lisa!!
