Genesis Basics: Darkening the Creases This is a small but important step that we must complete before we begin blushing. For our baby to look truly realistic, we have to add some depth to his little creases and rolls. To mix the tone for your baby's creases, darken your regular mottling color with burnt umber until you get a darker wine color. The consistency should be slightly less thin than that of your blush and flesh colors. It's important that this shade be the darkest blush color you use on the doll. Apply the paint inside all creases on the arms and legs with a small brush. Use your dry liner brush and a fresh cosmetic sponge to blend as needed.  The paint should be darkest in the creases and feather out gently on the skin. Be careful not to allow the paint to pool. (Don't forget the area between the fingers and toes!) Repeat this process for the head, making sure to include the inner ears, interior of the nose (remember to blend), the inner mouth, under the lower lip, around the eyes and nose, and the pouty area above the lip in addition to all the other creases. Bake again!
