This isometric pack contains walls going in two directions, in wood and stone patterns (all textures used are from this public domain pack by West: https://opengameart.org/content/wall-grass-rock-stone-wood-and-dirt-480), and two heights. It also contains a couple isometric tiles in wood and stone patterns, and has versions of the walls without the patterns applied so that different patterns can be applied more easily.

The tiles are 64 pixels wide. Heights vary but the tall walls are about 135 pixels high. The walls are meant to show be used for house/building interiors, although there's probably some other uses.

Edit: Added versions of the tall tiles that have doors on them!
