Who Spilled the Buttons?

It started as a color study at a meeting of Artrageous Quilters here at Cotton Fields Quilt Shop on May 5.  Finished tonight - unless I decide it needs more buttons.

Machine pieced, machine quilted, facing instead of border and binding.  Size 17" x 23".

Instead of studying color wheel and color schemes, we approached color from a more intuitive direction, noting what we liked about different combinations:  contrast, light vs. dark, etc.  It was interesting to note that, even though the center squares are all 2" and the next squares 4", their sizes seem to shift, depending on their backgrounds.  The three black accents were added both to add a little interest and also to provide more contrast in their respective blocks.
