This style of calligraphy is called Copperplate. Although I have done other types of calligraphy, this is by far my favorite and the one I do most frequently. I am trying to branch our a bit, but Copperplate is a very formal calligraphy. I will show you some variations that allow you choose something a little more modern if you want.
This last envelope that is gray had to be hand-lined which makes it a little more costly. I had a precious bride whose envelopes were dark gray, and she wanted hers to not be so formal but a "little funky" so here is an example of what I we did for hers.
Every envelope was a little different. The sizes of the names addresses and city and state were not uniform and I wrote them at all different angles. This was very intimidating at first, but ended up being one of the weddings I have enjoyed doing the most!. I have also done several larger pieces of work for a number of clients. Below are some samples of those.
