Op Art and Colored Pencil Tutorial - Art 1
Art 1. Printmaking. Wow! This lesson is so amazingly detailed - it's crazy. It's my understanding that this creative and dedicated teacher had her art lesson section of her blog hacked. This lesson on Pinterest is an example of what she used to have open to the public. I hunted around on her blog and am decidedly impressed.
