You'll need lots of wood.  Wood is used to make everything from the floors, counters, shelves, tables, and chairs.  You'll also need trapdoors and pressure plates which can be used to craft stovetops, tabletops, and the sides of chairs. Keep in mind that different types of trees produce different color wood.  Oak and Birch trees produce lighter color wood.  Dark oak and spruce have a darker color.  Jungle wood and acacia have a reddish tent to it. Cobblestone is mined from stone using a pickaxe.  Stone can be found underground and alongside mountains. Stone can be used to make buttons as well as for countertops and floors.  Use the following steps to craft stone:   Craft a crafting table from the wooden planks you made.  Craft a furnace using the crafting table and 8 pieces of cobblestone. Place the furnace and open it. Place cobblestone in the space above the icon that resembles a flame. Place place fuel in the space below the icon that resembles a flame.  You can use coal, charcoal, wood, or wooden planks. Wait for the cobblestone to finish cooking and gather your stone from the furnace. Minecraft has lots of materials that can be used to craft a good looking kitchen.
