Basic overview of the Compact Blocks Mod:
Have you ever wished you had a mod that took care of all of those extra blocks you have lying around? The Compact Blocks Mod will answer all of your prayers by allowing you to craft 9 blocks of a specific type into just one block. This mod means that you will have a lot more space in your game and won’t have to craft as many chests as you would before. The mod is available for the latest patch of Minecraft 1.7.4 and is also compatible with Minecraft Forge.
