This week’s email video lesson featured the humble ballpoint pen… a simple tool capable of creating soft, velvety shading — perfect for botanical sketches. Our subject was the prickly pear cactus and its frequent parasite, cochineal insects. (Spoiler alert: dried and ground-up cochineal are the source of the food coloring Red No. 4. Enjoy that bowl of pink yogurt!)
Next week, we’ll go fast and loose to draw summer birds. See you then!
