My four-year-old isn't that interested in drawing, but he loves sending and receiving mail. So to stimulate his interest in arts and crafts, we make 'I Love You' cards. It doesn't have to be a special occasion to send an 'I Love You' card, so we make and send cards to family/ friends throughout the year. To make it a fine motor skill activity, we often come up with different shapes to cut the cards in (hearts, etc.) and we practice writing.
