The sandstone line up was missing a block (or at least was in need of a redesign to be consistent with the rest of the blocks) : the chiseled red sandstone block.

Today I fixed it, using the same kind of pattern I used before, a side view of a skull (the same way the regular sandstone's chiseled pattern is a front view of a skull).
