Annie, on a slightly different path I am still experimenting with different papers for Kallitype. My primary disapointment has been the coatings do not stay on the surface enough. I have fround one paper so far: strathmore 400 watercolor. It will work for some images. I am curious if you or others have tried Arches watercolor (hotpress)? I have been told the surface is very smooth and it is sized.
