Technical Tip: After sketching your birthday moon, sketch how the Moon would appear three days later. Press the "Back" button on your Web browser. Change only the field settings for "Day" and if necessary, "Month" (all other settings should remain the same). Repeat the process until you have shaded how the Moon appears every three days for the next 30 days after your birthday.
