Just beautiful!
When you go to print them you might try printing on light weight watercolor paper or pastel paper. I really like Stratmore's Stonehenge line. It's 120lb, I believe but check the info first ... it is slightly heavier then card stock. The grain is good so it folds wonderfully without buckling. Stonehenge comes in a lot of color tones ... white, off white, cream, fawn, gray and black ... so you have some background choices.
I buy mine at Dick Blick or Jerry's Artarama. Both are on the web.
A lot of art papers have deckled edges as well which gives an extra touch to your printed cards.
Don't forget to pencil sign the printed card as well
