If you hadn’t already caught on, a painting doesn’t have to be too fancy to quality for 30 in 30. 🙂
These are tests of vellum in a little 3″ x 4″ book that I picked up at Daniel Smith in Bellevue. I really like this surface, but especially for pencil (just utterly fantastic) and pen (as satisfying as sweet potatoes in maple syrup).
I recommend a very fine point for pen work; the vellum tends to soak up a bit of the ink and widen the line. Witness the pen lines in the example, which were written with an XF (extra fine) nib. But also note that faster lines are thinner, so you do have some control over this.
As the right image shows, the surface also takes watercolor nicely.
