The Colored Pencil Society of America has an exhibit at the Glenview Mansion's art gallery in Rockville this month.* Deborah Maklowski of Columbia's Artists' Gallery has a few of her own works in the exhibit. Fascinated by the detail and intricacy possible in this medium, I had to buy a small sample by Maklowski last year.

(Maklowski works in other mediums, too, and her plein air pastel blog is in my blog roll. Her blog has also been a good source for tips on places to visit in the area.)
