Yes, it is March 1 in Australia, the home country for Happy Little Stampers. The challenge is always "anything goes." Grab your watercolors, make a card and share with us.
Recently I watched a video by Kristina Werner on You Tube where she used this exact stamp from Honey Bee Stamps (I already had it in my new supplies). She stamped it on black watercolor paper and colored it with beautiful glitter watercolors.
I had neither of those items in my supplies so I improvised. I had recently bought some black mixed media paper and I had Twinkling H2O's. These are very old supplies - beautiful shimmery watercolor in a little jar. You may have them hiding somewhere in your craft supplies.
