A quick update on the shields; all the blue edging is painted in, and I've washed the new paintwork with satin varnish wth a little blue ink mixed, to give it depth. Unfortunately, the flash has taken out the detail in the photo; the shields are starting to look very good, in real life. 2-3 sessions more work is needed; bosses tomorrow, I hope.
In answer to today's questioners, I've been using my fingers to hold them, rather than sticking them to a base. Whilst being painted, the curved shields rest neatly over my left index finger, which is now Porcelain Blue, and lightly varnished.
