Why Hippie Heart? Because the rich, luscious watercolors of this artwork reminded me of the joy of tie-dying, the fun process, the vividly colored dyes, and the serendipity of not knowing how this organic process would “paint” the t-shirt. Thats how I felt about this heart art when I was finished with it- and being a little bit hippie, and definitely a lover of bright colors, I loved it! This blank card makes a great statement of love, of friendship, of sympathy- whatever the occasion, a heart always speaks of love. The cards come packaged 4 to a pack with envelopes.
