Feed My Sheep is the most comprehensive of Barry Stebbing's art courses. It is a combined art text and workbook for teaching drawing, color theory, art appreciation, perspective, portraiture, anatomy, lettering, painting, and more to students in third through ninth grades. It is written directly to students; older students can work independently, but younger ones will need assistance and direction. This is a particularly good choice for parents without art background. As, with all Stebbing's, courses, it is written for Christians.
Since students are expected to work in the book, you should purchase one for each student. However, you are allowed to photocopy for children in your immediate family if you wish.
