My Yahoo group is involved in creating Inspiration cards from each other. We have prompts that we can choose from, and every other week, we send a home made card to someone on the list. Since I was hosting it, I could make the rules, so I put in there that the cards could be digital, since I always have so much fun making digital montages.
My first one is based on the theme: "this too shall pass"
Here's my interpretation.
I combined grunge and mail art, adding a postage stamp to the card after I printed it.
