For this DIY you will need;
Old children's books
You can find cheap vintage children's books at thrift stores, rummage sales, and yard sales. I find that a lot of these books have crayon marks in the books so I don't feel that bad about ripping pages out. But if you do feel guilty you can scan and print a page out.
My frames had old pictures stuck to the glass so I removed the glass and cleaned them, if your frames are old like mine you will probably need to dust them.
Place the glass from the frame over the image and outline it with a pencil, cut and then there you go. Awesome, cheap art for your home.
These bring a whimsical feel into my apartment, I'm a Disney fan so most of mine are from Disney books, but there are thousands of adorable books out there!
