I have had trouble finding basket illusion markers recently. I typically use the Faber-Castell Pitt Artist Pens but it seems like the variety of fine-tip marker colors available is much less than it used to be. There is still a large variety in the brush-tip markers but it is more difficult to color neatly with those. It seems like Faber-Castell is phasing out their fine-tipped markers. I am interested to see if anyone else is having this issue and whether they are using Faber-Castell markers for basket illusions and if not, what brands and marker tip types they are using.
