A very beautiful invitation, a very challenging envelope.
The paper has some natural fibers, possibly bamboo. The envelopes are lined with dark green rice paper - glued very well. So how to address? and quickly? Luckily the bride wanted this italic style, so I am using a broad edge nib - it won't pick up the fibers as much as a pointed pen would. Mixing a black gouache with Higgins Eternal - able to scrap off any small mistakes and burnish paper to then make corrections.
Despite these aspects, they are moving along well.
