:) That's exactly what I did with these books. Here are the front and back covers after alterations:
And here's a glimpse of what I did on the inside of each:
But the even cooler thing about doing these kinds of physical, altered books is that you can do high res scan of various aspects of the pieces and then make even more artworks. Here are a few of the pieces I've done in that process, and these are now available in my gallery as stickers, totes, journals and more:
This one is an over saturated, highly detailed scan of one of the paperdolls on the back cover, worked up in PSE as its own solo piece. You'll find it over in the gallery here.
This digital composite was from a shrine series and it incorporates the door featured on one of the front covers of the altered books. It actually incorporates high res scans and photos of 8 different pieces I created along the way. The shrine outline and composite was all done in PSE and this finished piece is in the gallery over here.
So can you see how you can start with old or unwanted books to create art? Then scan or photograph and make even more art? What ideas are sparked for you seeing this? Are you already picturing books that you'd been considering clutter which now might morph into art? What other items do you have around the house that you might turn into art?
Go play! Have fun!
