I response to your call for artists to submit artwork fot your silent auction, I have created a series of digital images using bicycle parts. The mandala below is the central piece and is intended to look best as a poster.
I am submitting a back & white poster of this image, a print of the image seen here and a box set of cards based on this image.
As I worked with these images, however, I realized that they have potential beyond the auction. They could be turned into products that you could sell all year around in order to raise funds for your services. Along with this idea, I have created some promotional products that should expand the possibilities here.
