I love to decorate every greeting card I hand out. My go-to items are stickers, markers, Google images, and stencils. I've also made a few pop-up cards. I'm always looking for new materials to use. Using pencil erasers worked really well. Newer ink is darker and requires fewer applications. You can add colorful polka dots, flowers, or anything else you can think of. Everything dries within seconds and becomes beautiful pastel colors.
