I38. Dr Martin's Bleed Proof White
A dense, opaque, smooth-writing white for your dip pen. Thin with water to the proper consistency. Tint with watercolor or gouache for pastel letters. Recommended by John Stevens and Peter Thornton. 1oz. Diane Von Arx uses a similar product, Pro-white (I62).
This works very well for watercolor painting. Quick delivery too!
While Dr Oh Martin's bleedproof white has many things it is excellent for, my favorite is writing with it. You do need to thin it, but a few drops of water suffices. Dip you pen and do a few test strokes. It will write a nice opaque white line. The more you thin it the less opaque. You can even write with it all the way down to almost transparency. Highly versatile, provides lots of flexibility for your art.
My Favorite white!
