White cards with a pop of color are such a classic. Check out this one that Kim made for our October Stamp Share swap:
Colors: Basic Black, Basic White, Daffodil Delight, Highland Heather, Mossy Meadow, Pool Party, Timid Tiger
Kim used Stampin' Blends to color the flowers. I guessed on the colors she used. The "hello" stamp and the shaped die are from Unbounded Love, and are no longer available.
