Envelope lining 6

This particular envelope comes from the UK. It came from the same set of materials as "Envelope Lining 5"-- a set of leaflets for the UK Charity Prostate Cancer UK , encouraging donations. This was the envelope the charity provided for donors to send in their donations.

The pattern of this envelope is a "herring-bone" pattern in blue.

Much like the previous examples, the pattern used is formed from fine lines. However, the pattern used here appears to be more complicated than the previous examples.
