Punmachine's Basic Textures
A downloadable texture pack
A free texture pack with 15 textures.
I may update this pack in the future. For right now I think I would just release another texture pack, because this is a basic texture pack and I want to keep this one on the smaller side.
Please be sure to read the license included in the .zip archive.
Download and extract the .zip archive to wherever you need the textures.
