I enjoy using non-tradition colors and here is a love card in browns, green, white and black to prove it. I used a lighter brown card stock for the base and the white is all basic card stock. The hearts use dark brown Bazzill while the thin border layers are basic black card stock. The green is some pretty DCWV double-sided heavy paper I got for Christmas. I used Spellbinders for the hearts and a Hero Arts stamp for the love sentiment. The brads are black American Crafts.
This card is for the "Love is in the Air" challenge over at Cards in Envy. The idea for the design can be found here.
