Here's my take on the card. I used a large poinsettia stamp, and then colored in the poinsettias with gold Twinkling H2O watercolors, and added some pearl centers and a ribbon bow. It's a little understated, but I like the sheen from the shimmery watercolors.
I really like this layering technique and think it would be fun to try with patterned paper, as well as background stamps. Be sure to check out the CASE-ing Christmas challenge!
