I’ve never had formal art training and dimension is something I’ve struggled with throughout my art career. I bought myself a book on how to draw and practiced cubes and spheres and cones. It didn’t help, I still don’t know how to draw and dimension and perspective continue to perplex me.
I’ve tried to develop my observational skills and discern which techniques create the illusion of dimension. Traditional quilts like Tumbling Blocks use color and value. One of my favorite quilts from the International Quilt Festival at Houston was “White Holes” by Peter Hayward. He used size and color to create dimension that was absolutely mind-bending!
