I wasn't sure I was going to get time to play along with Less Is More's challenge to use Complementary Colours this week. But I found this photo on Pinterest and that made it easy.
My colours are actually closer to the inspiration than this photo is showing - they look very blue. I used Aquamarine and Island Indigo cardstock and Only Orange for the letters (Soft Stone for the card base, to incorporate the colour of the headboard). I coloured the bottom half of the letters with a Copic marker to represent the 'fold' in the circle art above the bed.
