It goes the same for displaying your cards. I have noticed if a photo has no background color of some sort, that I seem to skim by unless something on the card pops out at me, but when I see a card like in the Stampin' Up! catalog I will stop and say " now that is a nice card, wonder what all was used to make it." They use photo boards. Photo boards for some could be costly but you can use anything to create your background. You could use a piece of tile from flooring, a picture from your wall, a towel. Just anything to create interest for your photo.
Now this is the same card but on a wall hanging I found at Walmart and used it to be my photo board. See how the photo pops. I first see the stamp pad and then I follow along over to the twine and then I look at this stunning card! I then continue on to see what other elements are on the board to end with the die cut image. I am saying to myself "Oh, I like that rustic look, and where did they get the buffalo check at?" so now I am going to see what else they have to show about the card.
