Vintage fabric #4 burgundy cubed geometric(2.8 yards)

This fabric is super cool and thick. If You look at it one way it looks like diamonds on it, but another way and You can tell they’re cubes. Reminds me of q-Bert video game.
This is burgundy and navy blue. 104×45 inches, just shy of 3 yards. This is from the late 70’s from what I understand
