Our florist suggested going even further with the "assorted" look, and incorporating these coffee cans** as well, since they match our color scheme:
These images above via Style Me Pretty show great examples of both -- all clear glass and mix 'n match vessels. What do you think will look best?
**Update: We went to Cost Plus where they sell this coffee, and the cans look much more orange in person than they do in this photo. TOO orange. It's overpowering. So I don't think we'll be going with the coffee can idea after all, and we'll stick with a clear glass palette.
