I am loving the walnut ink, love the variations in shade, and also the feel, I didn't get to messy mixing it, which is a Bonus, and Andy T thank you for the ratio advice and everything, I think I have mixed it correctly.
I found two things, firstly make sure your nib is correctly primed, ot the ink slips off, plus you dip more often, but neither are an issue, and I have enough ink to be going on with.
Oh also it shows up flaws in my script which is what I wanted, so this means now I can look at those and correct them.
so here is my walnut ink practice, warts and all....
I will keep this, then check back after a week of writing to see if I have managed to correct my issues.
Have a great day
