A college degree program is helpful. And usually required for many certifications.

Thank you, Sophie. I can certainly see how a degree would be helpful. Though after several years of teaching, grad school, and researching in the education field, I'm finally able to stay home full time. With a little one at home now, I am savoring every moment. I am a researcher and learner at heart, though, and as I seek to make my home more beautiful, I am realizing more than ever how much I just don't know. I'm looking into taking an evening class at a local college. Do you have any recommendations for types of classes I might take? Are junior/technical colleges worth the time? And are there books that you might highly recommend to someone wanting to understand design better?
