If you haven’t joined the band wagon of coloring, I created a Floral Coloring Page for you to make your own cards. Click here for a copy that you can print yourself or take take to your local printer. Print on card stock for best results. For colored pencils, I adore Prismacolor and buttery Faber-Castell Polychromos. Keep your pencils nice and sharp for crisp lines and fine details.
Paper Source has a vast selection of colored envelopes. Keep snail mail alive!
