It annoys me also when teachers don't let their kids take their work home
after I told the students that they could. The teacher's response is, "These
are cute. I need to hang something out in the hall."
How about asking the teachers if they want to display some art for open house
in February then you can help them out with a lesson in january? This way
they will know that they can have some beautiful work to display and won't
have to be squirreling away the student's art in September.
BTW, the color wheel name design sounds cool.
