A vintage Persian Flatweave. The slit-tapestry (kilim) technique lends itself to triangle ornamentation which, taken to its limit, means that every decorative element is or is made up of triangles. Here three nested diamonds are detailed in lemon yellow, rust-orange, red, light blue, teal, dark blue, khaki and ecru. Triangle chains and doubled triangles decorate the borders of this rigorously geometric pileless rustic long rug.
