I bought a Koi WaterBrush because it’s so compact but it’s now my favourite. With some water brushes I can squeeze and squeeze the barrel and not get a drop out, then I squeeze again and get too much. The Koi gets it about right for me.
“I really liked the Koi brush, too.” writes Julana, “My only issue with it was that it didn’t hold a lot of water. I guess you could carry a few at a time.”
I agree, because I’m surprised how soon I get down to having just a few drops left. Luckily, it’s not a difficult process to refill, once you get used to the fact that you turn the barrel right (anti-clockwise) to unscrew it.
I’ve worn the point off my first brush and the current one (top) is starting to get worn down, so I’ve just bought a third.Sakura recommend that you clean out the brush after every use and suggest that if you’re leaving it unused, you should empty it. This could be why I have trouble with the valves of my less-used water brushes; I always leave them full.
They also stress that you should never lose the black stopper for the barrel, but I’m not sure why this should be so vital, once you’ve assembled the water brush. Perhaps if you were aiming for the ultimate in a compact watercolour set, you could keep the barrel separate but ready-filled with water. You’d fit it into a box that was just three inches long.
When I replaced some of the colours in my Winsor & Newton bijou watercolour box last year, some of the original selection weren’t available so I thought that it would be worth doing another set of swatches to familiarise myself with the new palette.
I’m always impressed by the variety of colours that can be mixed from such a small selection; basically a warm and a cool version of the three primaries with a few useful secondaries, such as sap green and my go-to colour for so much natural history, yellow ochre. I find neutral tint useful too; more versatile than black.
It’s always good practice for me to paint swatches, and to try and hit that midway point between the two colours that I’m mixing. It’s also rather therapeutic to settle down for a while, listening to Radio 3 as I mix colours.

The four cream ‘shaving brushes’ on the back of the Vapourer moth caterpillar, Orgyia antiqua, make it easy to identify and presumably make predators think twice about trying to eat it.
This was nibbling away with three or four vapourer caterpillars on willow leaves by the woodland ride at Thorpe Marsh nature reserve. Larger numbers of vapourers can have a devastating effect on city trees.
The wasp beetle, Clytus arietis, does a good job of mimicking a hunting wasp but is harmless. Its larvae live in deciduous timber.
This one was taking a break on a dog daisy growing at the edge of a woodland ride, once a railway, on the Yorkshire Wildlife Trust’s Thorpe Marsh nature reserve, near Doncaster.
