Here is a cool High School Lesson where I introduced Pop Art and the work of Roy Lichtenstein to my students.  I showed them some examples and discussed the meticulous use of benday dots.   The students first searched for a magazine image of their choice.  They then traced the image using contour lines only.  They then transferred the image on white paper using charcoal transfer paper.  Next students outlined their image using a black sharpie.  Students then began to paint their design using primary colors only.  I had my students use Q-tips for their benday dots, some chose to use a ruler aswell to line them up properly.  Remind your students to practice their dots on a seperate paper prior to beginning.  Once students are done with their dots they will use black acrylic to paint everything they outlined in sharpie.  I had my students add a caption to give their design a more comic book effect, however it is not necessary.  Have fun🎨
