Painter and teacher Catherine Kehoe has a wonderful blog geared towards painters and painting students. She is doing a great series on artists and their palettes, provides wonderful quotes on painting, and summarizes some great kernels of wisdom from artists like Charles Hawthorne, E. Dickenson, etc.
On related note, I am lookng forward to seeing "For The Common Object," a show by the Zeuxis group of still life painters, of which Kehoe and one of my former professors are members. The participating "artists...agreed to produce a still life incorporating an ordinary dishtowel. Their approaches to this humble tool of daily life demonstrate the many ways in which still life painters can, in the words of John Updike, 'give the mundane its beautiful due.'"
