Every time we get a new ink for our fountain pens, I use a pen and write a sample of it into my journal in the back. That way, I have a running list of the inks that we have, and can see what they look like.
I also record which pen I used to create the sample because inks perform differently, depending on the nib and pen used.
Finally, I am practicing my cursive writing, which is important, because I am trying to improve it.
Do you use a fountain pen? If so, do you use it just for writing, or do you also sketch with it?
Fun!
