I'm not a trained artist but love to paint. Here is how I painted books on shelves. It was so easy even a cave man could do it. I take that back, some of those cave paintings they did outshine anything I could ever do.
Step 1: PAINTERS TAPE IS YOUR FRIEND
I got the idea from a picture. You can see it in the upper left of this image. I used painters tape. I measured out 3 evenly spaced shelves about an inch thick and taped them off and painted them brown. How easy was that?
Step 2: I DREW RECTANGLES
On each shelf I drew a bunch of books, varying the size, shape and position.
Step 3: THE BACKGROUND IS THE NEW BLACK
Then I painted the background of the shelf black. I also outlined each book in black. This simple separation from book to book really made them stand out better. See, I told you this was easy.
Step 4: A RAINBOW OF COLORS
Then I taped off each book, painted it a different color and gave it a very simple design.
Step 5: GET OUTTA THE WAY VAN GOGH!
What I ended up with was a very colorful bookcase painting. My son liked it so much he wanted it for his house.
Step 6: FRAMED
I framed it and gave it to my son. Then my other son wanted one and that is the image I used to start this Instructable. In that one I wrote the name of authors whose works I've read. And I didn't even bother to stylize the authors' names. I just printed them.
Seriously now, how easy was that?
And don't say a caveman could do better because I'd agree, but I paint for my own creative pleasure and I hope you enjoyed the final result.
Now, everyone sing: Butterfly in the sky.......
