Position the sharp end of the protractor on the doll blank where the doll's irises would be, and make gentle indentations in the wood.
Pencil an outline of the doll's eyes around the iris nicks. Draw the doll's face and hair.
Draw the doll's outfit and final facial and clothing features on the blank.
Paint the back side of the doll with the acrylic paints, using a wide paintbrush. Fill in the larger areas of the back of the doll with paint. Use darker colors first. Lighter colors can be added later.
Let the main back and body of the painted doll dry for several hours.
Use finer angled or tipped paintbrushes to fill in the details of the doll's face and body. Use dark colors first. Let the paint dry for several hours.
Highlight the doll's eyes, irises, hands, and clothing features with white paint and other lighter colors. Let the doll dry for several hours.
Repeat the procedure to paint each doll in the set. When all the dolls are finished and their paint has dried, coat them with a spray-on or brush-on clear acrylic or wood varnish sealer for protection, and let that dry.
