Here's the next creative idea, using pictures on your cards. I got this idea from the Paper Craft magazine issue Paper Crafting with Photos. I got the photo from Paper Crafts website, but I can't find it now that CK has taken over.
You can really use any picture. This one was in color, I turned it black and white and printe it out on Close to my Heart's textured White Daisy cardstock to give a linen look.
Have fun with your photos. . .
