In “The Art of Mark Making,” Ashley Andrews and Natasha Karpinskaia collaborate on a series of paintings that revisit Abstract Expressionism. “We intend to show the positive effect of teaming up to make new intriguing marks,” the artists said of their partnership. The paintings become a dialogue between the artists, as one begins by making her marks and the other responds. As the process repeats the marks are changed until they no longer belong to Andrews or Karpinskaia alone, instead becoming something exciting and new.
