Built using Bookshelves, Hatches and Ice Blocks. (Only easy to make in Creative Mode)

Cover the side of a grass block completely and only expose the top.
Note: to have a grassy top in survival, you will need to grow it by first attaching your block to an existing grassy block. Read more on this method on the Minecraft Wiki page: http://www.minecraftwiki.net/wiki/Grass
