Art doesn't have to be big. Art can be 4" by 6", if you really want.
I'm doing a new swap over on Craftster where you create a 4"x6" piece of art and then get a partner to send it to -- I had participated in this swap a few years ago and just found a photo of the piece I sent along.
I am beginning to realize how much I enjoy collage. This piece involved a little bit of everything: paper I had inked and embossed, origami paper, images, words, rick rack, markers.
You can see more of the texture here. I was really happy with the vintage look! Now I'm even more excited to work on the next one.
