How do you take a 6" x 6" collage and turn it into a 30" x 60" painting? That's my current dilemma. I started one last night, there are two of them. The client who ordered these paintings told me that they will be going in a corporate office in California and that the people who bought them just love my work and have designed their office around my paintings. What? They had tiny little squares to look at. How do you design an office around that? Well, guess I should commend the sales efforts of my client.
