Helm pattern for Jared

Jared, sorry didn’t see your facebook email 'til just now. Here is a rough pattern:

Of note:

  1. This is basically half a rugby ball.
  2. If the points marked with the orange circle are 90 degrees, you get a flat top. If they are less (70 degrees) you get a point like a rugby ball. Don’t make them more than 90 degrees, because 4 x 90 degrees = a full circle.
  3. Make the circumference a few cm bigger than your hat measurement.

I really need to try making one of these. I’ve got a flat-cap, and a great helm, but spengenhelms would be useful.
