I had to add a circle, I just had to. I'd been missing them. In 2 of these pieces of mail art, I used some very pale colors, with not much contrast.
I used some brighter strips in the second set of two pieces of Mail Art. I'm not fond of bright colors. I have to force myself to use them.
I think this will really make sense to the recipient because they'll feel the different surfaces of this card, which can barely be seen.
