Journal Pages make great postcards, and a great way to share art.
Some of my best collages have come from adding bits of mail art, both received and sent.
Try sharing your work this way, and see the inspiration blossom.
"If you have an apple and I have an apple and we exchange apples, then you and I will each have an apple. But if you have an idea and I have an idea and we exchange these ideas, then each of us will have two ideas." --George Bernard Shaw
