Blueberry twig greeting card

I was charmed by the simple beauty of a blueberry twig that I found beneath the bushes while picking berries on Saturday.  I drew the twig this morning, then turned the drawing into a blank greeting card.  The card is heavyweight card stock (130lbs) and the envelope is watercolor paper - the only heavyweight paper I had on hand in a large enough size to accommodate the roughly 4x8" card. 

I don't know who I'll send the greeting card to yet, but deciding will be fun.
