Here is my card for yesterday's (6.11.12) white-on-white challenge. It is also for today's MMTPT202 challenge.
MMTPT202 Flowers for Regina by gabalot - Cards and Paper Crafts at Splitcoaststampers
I've used a white card base that I stamped in light lilac w/an Andy Skinner bkgrd stamp. Using dimensionals, I added a white panel that I stamped w/SU Elements of Style and watercolored.
Thank you for looking!
