Time to put this card together… so I used double-sided tape to adhere the vellum to the watercolor background. I make sure to score, fold over, and tape down the excess to get a good hold. I leave the right hand side flapping about so that you get a little pop of color every now and then as you hold, open and close the card. The vellum does a great job of obscuring the imperfections in my coloring without taking away the beauty of it.
