So how are other Etsy card artisans upcycling?
Here are a few designs I simply adore...
These cards were crafted by PinkFlamingoCrafting from old sheet music, maps, book pages, and crossword puzzles.
This set of cards, created by SimplySweetNothings, was upcycled from old Curious George books: I love the scenes added into the envelope backs! So cute!
And this lovely collaged crown, designed by JaneKoopman, is made from a set or authentic (and international!) stamps. Love the colors and theme!
