If you are looking for an easy way to zhuzh up a library or anywhere you have shelves, give this a try:
Turn the bindings of the books towards the wall ( to be fair if you want to find a book, this is not the way to do it) so the edges of the paper is turned out. When all the books are turned around, it gives a more uniform look. But don’t stop there, stack a few books down, create gaps on different sides, and in general just create a sense of variation.
With small interesting pieces, look for repetition in color to place throughout the gaps. Vases with fake flowers, candle sticks, candles, plants, clocks and more! If you’re looking to change things up, give it a try!
