Here is what I made for the classic color scheme:
The card base is grey, the sentiment, paper, and flower have white, and the paper, ribbon and flower have black.
Here is a close up on the white embossing powder detail.
Here is an angle shot so you can see that the flower is popped up on dimensionals. Plus, it's a fun way to view a card!
Here is a final shot! I think this would be a great wedding card, especially for a couple that chose a more formal monochromatic color scheme.
Have an amazing day!
