I found that it was hard to doodle with my white Uni-ball Signo pen on this page. This was a surprise since the page is supposed to be dried ink, so I was not expecting this to not work well. My black Martha Stewart Calligraphy pen pigment ink worked perfectly, so I decided to doodle with that pen and also add my journaling.
I added some touches of white gesso at the end and I was really pleased to see that it did not reactivate the ink even though gesso is waterbased. This confirms that you can add-on any new medium to this background. Here is the finished result:
As with all water-soluble pencils, you can put a wet brush onto an Inktense pencil to pick up some ink and then brush this onto paper. It works very well when you want to add highlights to a project or if you want to color a stamped image.
