Some of the hardest cards to make are either sympathy and thinking-of-you cards for serious occasions. The idea of two neutrals plus one color is perfect for creating that much-needed soothing feel to a card. Consider these two cards.
The card above is for a friend who definitely needs to find peace with a difficult situation. White, gray, and dark blue give a soothing feel, while the sketchiness of the flower acknowledges how crazy challenging finding that peace may be. (Or am I going too English major on the interpretation? I just never know.)
This sympathy card uses VersaColor Cement, which is a wonderful taupe-y gray and Paprika. The smallness of the sentiment and the single colored sprig don't matter given how the Paprika dominates without overwhelming. Soothing, understated, sincere.
On both cards the colors are strong, but by using so little of them, the message comes across clearly without being shouted.
