pinder-
I've only seen a yellow emblem made of gabardine and not lycra, but GELForever says otherwise, so I'm guessing either one would be correct, but I'm leaning more towards the lycra which would be why the emblem looks curved. The emblem has the black lines embroidered into the material and I believed that it was embroidered separately and sewn onto the cape later on, but I guess Mantis and MisterFusion can answer that.
misterfusion or Mantis- Can you tell us what the width of the cape is? I saw a real one once, but I never got to measure the exact size unfortunately.
