Chevrons to Eva

Eva and I had had a small conversation about where the airmail edges on envelopes comes from. I always thought they were called chevrons, but they're actually not chevrons... and parallelograms just doesn't have the same ring.

Anyway, along my search for airmail chevrons and their source, I came across some printed envelopes by Alan B.

So I decided to print some chevrons on envelopes myself, and the Summer Harvest stamps seemed a good match.
