Of course you can, a month ago Sharon Tomlinson gave bloggers a challenge to carelessly paint a background and find things in the painting, it was a good exercise as it made your imagination
work, and it gave one a chance to paint freely. I talked about Sharon in my profile and her influence.
Often when there is paint left on my painting plate, I just use it up doing a background. It makes me feel bad to find a dried up paint plate with wasted paint. I put the paint on the paper with a painting knife which explains the texture. Often ones finds nothing and that is because we have thee ideas of what we would like to find. I wanted to find a womans face and one that would take up a lot of the space. It sat there while I worked on something else. Then I saw this tiny head,
and a great dress. Well I didn't really see a face I saw a head. I saw something on the head.
The dress made it look windy and it seemed night on the painting. I drew in the face with ink,
and I drew the hand. The bright colors on the bottom I just drew flowers in with colored pencil.
The colors were there.
This is painted on brown paper, when I scanned the painting I used a piece of scanned fabric behind it. When I prepare it on the computer in photo program I bring the fabric scan up first
then lighten the tint and change the color, then add the painting and blur the edges. Add a border.
This is how I would use it for a card.
