I used Spectrum Aqua Markers - Teal, Navy and a Spectrum Noir Sparkle Pen - Starry Sky to watercolor the night sky on Spectrum Aqua Extra White Watercolour Cardstock. The sparkle from the Sparkle Pen, mixed in with the Aqua Marker colors, gives a nice overall sparkle.
I added some white die-cut stars covered with glitter and gold sequins stars. The die-cut houses border has some glitter added for "snow" .
