Marcia,
I used McCaffery's white--not the ivory. Since I worked with Bill Lily, I follow his recommendation and use a Gillott 1068a, his and now my nib of preference. The nib, a stiff one, works well for me since I do have a heavy hand! I was fortunate to receive as a gift about 50 bronze Gillott 1068a's from Chris Yoke, a very dear man. The bronze nibs are nothing short of superb ones for my use. Bill Lilly simply adores them, so I gifted several of them to him some months ago.
With the Cansons Mi-tiente which I use often, I do make sure that the McC's white---and all other pigmented inks--are a tad thinner. I do not mind real stiff ink, but I find that it does not flow as well on textured paper, such as Cansons Mi-Tiente. I hesitate to thin it much, as I want the thinnest of hairlines.
I am in no fashion a professional scripter, but just a now retired man who adores the engrosser script alphabet and the challenges of mastering it.
Watch, as I will post more photos.
Thank you for your kind inquiry.

The silver ink is J. Herbin's calligraphy ink, which to my surprise works very nicely.
