Sometimes it all comes together...the media, the paper, the layout...
I've been using faux walnut ink with a bit of brown gouache for opacity and this envelope I really like. This is for a wedding and fortunately the envelopes are nice and big which gives you plenty of room to maneuver. In this case it is engrosser's script with slightly larger proportions for the caps on the first and third lines which gives a great contrast. The middle line actually has the proportions as recommended in the "bible" of engrosser's script, The Zanerian Manual.
