To be completely honest, this card was a bit rough. I am not as experienced with the old type calligraphy featured and my spacing was definitely not stellar. It is the first of many steps toward better calligraphy.
When doing medieval-esque calligraphy, it is important to use grid lines and make sure that the letters proportionally match up. I was really rushed while making this card so I did not make a grid like the one below. In my card, you can see that the two Ts are very different (the first is clearly better than the second) and all of the sizing is off.
My modern calligraphy was pretty good on this card. A really good tip for the letter 'd' is to make sure that you start the down stroke on the stem of the letter farther away from the rounded portion because the thicker strokes take up more space. I did not do as well on my 'p' as I had hoped for, I got a bit thinner than the rest of the thin parts of the lettering and it also became a bit wobbly.
