Mark a book!

Well, for most students, boredom means classes, n even though we dont (really!) advertise doing all this in class, we indeed did all this in class.
Out of sheer boredom, we started folding and cutting paper, which soon became like a pastime for most classes. The cutouts started becoming more and more intricate and we ended up making bookmarks with them. All we needed to do was paste them on hard, coloured paper.
This technique doesnt require any specialisation, as you can see how even the most basic designs can look pretty when set against the right background :)
P.S. we did the cut-outs on the thin notebook papers. You can try with different papers and share your experience :)
