Scour the internet a tree or other object you would like to trace.

Hook your computer up to your projector. Now shrink or zoom in on your picture to make it fit the canvas. Remember to try the image on the canvas vertically, or horizontally. I went horizontal with mine to made a wider image.

Use sticky tack, or some other temporary adhesive to attach your canvas to the wall.

*This is what my canvas looked like with the image projected onto it.

Now trace your image with pencil. Remember that you can edit your image to remove branches or add branches.

Once you're finished tracing, shut off your projector and double check your work. It would really stink if you took down your work only to see a huge chunk that you forgot to trace.

Lastly, fill in your traced image with paint. I just used a sharpie on mine because it was just a mock-up of the real thing.

Now you've just made yourself a super sweet, totally "done-it-myself" guest book.

Try to resist the urge to fill the canvas with your own thumbprints. I filled mine just to see if my canvas would be big enough for 200 thumbs. I also wanted to show you what it would look like filled with thumbprints.
I was able to fit a little over 200 thumbprints on my canvas. The total cost for this project was $2.30!!!
