What the title says. Building without half walls can be so difficult. When you only need a wall piece that's half the length of the regular sized ones, you're kinda SOL unless you use plaster or something else with extra building pieces. Plaster is fine, but it gets kind of boring after a while. I'm trying to build a mud hut right now as a shelter, but it's proving impossible without half walls. The regular ones are just too long for my purposes.
