I recently saw a blog post from a paper artist in Europe. Her style is so bright and fun, and she often uses paint to create the backgrounds for her stamped cards. I was intrigued by a card she posted recently, and she included a link to the artist's video that demonstrated the technique she used, called the faux print look.
Here is a link to her blog post: http://somefiddlingonthekitchentable.blogspot.com/2016/04/faux-print-look.html. And here is the link to the video tutorial she referenced: http://www.kimdellow.co.uk/2016/04/video-get-faux-printed-look.html.
I was impressed with how easy she made it look, and couldn't wait to give it a try. I got out the very simple supplies needed: cardstock, acrylic paint (the cheap craft paint works fine), and an old plastic gift card.
Following her directions, I spread thin layers of paint across the surface of the cardstock, leaving a white border around the edges. Because the paint is so thin, it dries very quickly. It is so easy to make several backgrounds at once and have some on hand.
