Wow, how did you make the bookshelf?
So first you make an 8 wide bookshelf thats 2 bricks tall. Next add 2 1X6 flat tiles so it's totally flat. Add a 2X8 with studs on top of that. Then gather lots of colorful 1X2s with studs. Make sure you have 15 of them, and one of them is a flat 1X2 tile. Connect them in a random pattern and place them inside the shelf.
Then with the 2X8 you added on top of those, repeat the steps until you have made two shelves. Then place 2 flat 1X8s on top. then you have a bookshelf.
