When you have lots to do and no idea where to begin it's time for a cup of java and some experimentation. I pulled a couple new markers onto the worktable, grabbed a piece of Yupo and tested some marks that I like to use in different ways.
I layed down a group of stripes in different directions and waited for them to dry. My expectation was to drag some sharp objects across the surface to scratch out some marks. I tried using some T pins I had close to hand. Surprise, the Yupo stubbornly held on to the ink. Well, ok that was a discovery I can use in the future.
That lead me to laying down some marks and then moving the still wet ink with the T pin. I used the same motion to create a similar mark. Some new things to think about and use.
All in all a very productive day.
