Thank you for the review Sandy - wonderful as usual.
You mentioned dilution to open up the ink - could you not just use Diamine Prussian Blue to experience a lighter shade instead of diluted Denim?
I have Denim on the way to me early next week and will also review it once I have the Diamine GreenBlack out of my Onoto.
Thanks for mentioning the Prussian Blue, even though I was hoping to dodge that one!
Indeed, when swabs are the means of comparison, there is more than a passing similarity between the two inks. I believe the difference becomes [more] apparent when written samples are compared.
. . . so let's all get bottles/samples and see for ourselves. Whee!!
