We have recently found a new paper for all of our JNB pads. It is smooth enough for pointed pen, but also works great with broad edge. I tested with Higgins Eternal, McCaffery, Pelikan and several Noodler colors....NO feathering! We have it in plain graph (items P21 and P22), copperplate graph (item P01) and blank (items P20 and P25).
If you want a FREE sample sheet, please let us know when you order or send me a PM with your address.
We used to use an HP paper, but Higgins and Pelikan both started feathering. I tested 20+ papers before I found "the one".
Cheers,
Michael
