One shouldn't use bristol with pastels...and I was reminded of this while drawing Sugar. Though the paper has a matte surface, there's not enough tooth to hold the powdery pigment. Similar to how a chalkboard receives the chalk yet, just as easily, allows you to smear the powder about. yeah.
Given all that, I felt compelled to finish. Even though this isn't the final pose, it was fun to draw her in the garden. More soon.
