For my card I used a 140lbs watercolor panel and I applied water where I wanted my colored banner.
I used Distress inks (shaded lilac, broken china and Mermaid lagoon) and one Spectrum Aqua marker (orchid) to deepen the purple a bit.
I heat set it and then stamped the sentiment from Simon Says Stamp (it's your birthday 3x4) with Versafine black onyx ink. Heat set it too.
Then I used the snowflakes from Lawn Fawn's winter penguin and critters in the snow and I stamped them with Versamark so I can heat emboss them. I used Wow! Opaque bright white for that and the MISTI as it's watercolor paper.
Mounted the panel with foamtape and adhered is off centre on the cardbase. I like more room at the bottom as it makes the panel float instead of heavy to the eye.
