No matter the reason I always have some kind of painting set up to work on. I still have my old paintings from school, always with the intention to add to them so I will like them. Right now I'm working on a contest that a large part will be painted.
A few years ago I had taken some photos of my self trying to convey the feelings I had at that time in my life. I don't remember having any kind of display plan for the pictures. As soon as I had the photos in hand I knew how I wanted them displayed. That was when I "created" the "Photo Painting."
This is a simple project to put together
Start with a canvas
Pick the photos you want to use
Tape or glue the photos into place
In some cases I have painted parts of the canvas before placing the pictures down with glue. When I do this I make a mark for where the picture will be (draw around the picture with a pencil).
If you didn't paint a clean line around the edge of the canvas you'll have an unfinished edge, I would suggest you pick a color from the painting or black and paint the edge of the canvas. This will make it look finished.
Not everything on the canvas has to be a photo. This craft is all about having a good time and showcasing your photography.
