Here’s the complete water feature, with two layers of varnish applied over the painted water and photographed under a daylight bulb. The water effect sort of works but has some problems the photo doesn’t reveal. I applied a second coat of varnish too early and there’s some crackling between the layers that is visible on close inspection. If I’m going to use that polyurethane varnish again I think I’ll go with one coat only.

Turns out Lighting Plus in Auckland sell ‘daylight bulbs’ that fit a normal household socket for $8NZ each and as Steve points out below they are indeed blue. Picked up a couple this afternoon as well as a ‘hobby light’ (light / magnifier combo) that they had on sale for $30NZ.

The Mordheim canal tiles are slowly progressing through various stages of drybrushing. I’ve also finished the experimental water feature but I’m not entirely happy with it. I might have to go with some decent resin water effect for the tiles - which means finding a cheap source of clear encapsulating resin in Auckland somewhere.
