This should be a fun challenge to watch. Sadly, I really don't have time to participate, but I'll be following along to see what everyone comes up with. If you're interested - check the link below to either participate, or just enjoy the eye candy as I will. The idea is to choose a single colour to create a monochromatic work of art. It can be jewelry, mixed media, collage etc.
