The first room I went with was adjacent to the closet. As you can see, I may have gone a little crazy with using a mix of materials. I thought it would look nice but it seems a little too... diverse to me. However I could just use that as the theme of the room.
All the way in the corner of the ravine, on the other side of the hall of the underground lake, I had a small squarish room and I decided to make it a Nether room.
Then one of the larger rooms, I decided to use a plank and wool combination. I want the ceiling to have light gray wool. There's a story connected to that: I needed more ink sacs so I went searching for squid. Every time before now I remember seeing tons of squid in the water my house faces. But they weren't there. I found them after some searching and collected their sacs. Then while crafting the light gray dye my game crashed! I loaded it back up and, because the items were in the transition state between inventory and crafting menu, they were gone when I reloaded. All that work for nothing. Need to find more squid.
Another problem I was facing is that I couldn't come up with good combinations of blocks, so I asked on this thread of the Minecraft forum. Here's some things I may consider trying:
- Iron blocks and lapiz lazuli blocks.
- Sandstone and Nether brick (need to find a Nether fortress first).
- Cobblestone and pine logs.
- Stone slabs with something.
- Sandstone with stone bricks.
- Sandstone with pine logs.
- Wool with wood or planks.
- Sandstone with red or blue wool.
- Iron blocks with obsidian
- Bricks with planks and wood.
