About this envelope
Square envelopes take square cards, 148 mm and 145 mm are the common ones, and they cost extra postage in most countries, which is why they are an invitation format rather than a mailing one.
A pointed flap on a square envelope meets the centre, which gives the back a diamond pattern; the mockup folds it that way.
Black paper with a light print and a printed liner is the premium invitation look this page opens on; the example art switches to light ink on dark paper.
Questions
Why do square envelopes cost more to post?
Most postal services surcharge non-rectangular mail because sorting machines are set for standard ratios.
