I wasn't sure how to handle this one. I started with my micron 1 in purple and realized it didn't work well on this paper. I had used Photo paper in matte finish because it fit in the printer and is really, really white! But it won't work with the micron pens, only with the fine tip sharpies.
So I shifted over to the sharpie and continued on. The ultra fine tip is about equal to a micron 5 so it is darker and thicker. I like it with the larger pictures. On a true tangle tile I need the finer micron 1.
