Art Cards fly through snail mail to deliver your news, gratitude, thoughts and loving messages with style and grace! Sets include original paintings on the front and blank interiors with matching envelopes. Sets are beautifully packaged in cellophane for protection and pretty presentation. All sets come with 10' of hemp twine so you can fancy them up in your own special way! (Red Thread Birds come with red cotton yarn). Use them as gift tags or letters to loved ones.
