The Insides of Envelops

I've been collecting these for a while. I can remember the day when I suddenly became fascinated with the insides of envelops... security envelops to be precise, with their different patterns meant to protect the information inside from prying eyes. They're not all the same you know. I wonder how one becomes an inside of envelop designer...?
Anyways, here is my collection:

Australian Super

Westpac

Diamond Spiral

Blue Wavey Plaid

Fish Scales or Blank Rainbows or Stacked Plates

 

The Brick Wall

THICK Scalloped Edging or Waves

THIN Scalloped Edging or Waves

Slanted Grid

Raised Slanted Grid

Speckled

Grey Wavey Plaid
