So much relieved, I pressed on with my signwriting practice, having bought a new paint brush of the right type. I find that I can paint pretty accurately as long as I have a pencil line to work to, but not if I don't, so I have stolen from Grace not only her watercolour paints to practice with, but also a nice white crayon that writes on top of painted steel.
In true boat painting style, I worked on a near vertical surface using a mahl stick as arm support. The only thing I couldn't simulate was the gentle rocking of the boat. Woe betide anyone that steps on or off the boat while I am signwriting.
Just to get you worked up into a frenzy of excitement, here is a letter B, somewhat distorted by the camera angle. Note: these are definately NOT the colours I will be using on the boat! The bottom of the letter would be straight on the real thing as it would be masked off.
