Hello Alba!
I’ve take the same workshop like two months ago.
I had only couple of hours by train (I never flew with nibs, so I can’t say what would happen), and I was very nervous too
I packed my suitcase with almost all the things on my desk, and then what I used is what I bought from her.
Usually she always bring the material for the students, and she also have a little range of other material too.
If you have other oblique than the speedball bring it with you! It will be very comfortable to switch from a nib to another. At that workshop we used NikkoG and Principal (She lent us some of her holder with strange nibs, but the two that we used for writing was that two).
She usually arrange a very nice welcome kit to the ws, with a lots of practice sheets and others gadget (I have a spencerian water too )
I think the only things you need are:
- obliques
- dinky dips with dropper
- irongall ink (preferably McCaffery's)
- Rodhia A4 white (no ruling)
- some nibs (just tbring small amount so although it will be seized will not be terrible)
She will wrote letters on her piece of paper and it will be projected on a big screen, so you can watch her, take some notes and re-do the same. A pencil would be great for this, also should be useful for drill exercise
Relax and have fun! it will be great!
