Here are two cards I made combining the new colour Marina Mist, with Night of Navy and Very Vanilla. I really like this combination, it is quite elegant and would be great for wedding invitations or cards. To me the circle stamp in the Just Believe set has a bit of an oriental feel to it, so I will have to experiement with this more at some point.
Marina Mist is a very pretty blue and would also combine beautifully with Bashful Blue for Baby Cards.
The new Colour Coach from Stampin' Up! suggests you also try this colour with Real Red and Old Olive, which would be great for Christmas, or Crumb Cake (Kraft) and Cajun Craze. I think this last combination would be great for male cards.
Stay tuned and I might share some of these combinations with you on a future post.
