During a routine dental check-up some years ago, my Greek dentist once caused me some alarm by announcing that he was going to begin his autopsy. Noticing my rabbit-in-headlights expression, he calmly explained the etymology – the Greek translation of the word is something like ‘seen for myself’. I’m not the most relaxed dental patient and it was helpful to have this (slightly nervous) laugh at the time.
And of course, seeing for yourself is always the best way to learn. I drew some masking fluid on a page of my colour palettes sketchbook before adding watercolour. And – surprise – it doesn’t work.

You can see where it was, and it does act as a resist of sorts, but it doesn’t rub off in the normal way when the paint is dry. It lies underneath as a separate layer and sinks into the paper rather than sitting on the surface. I’ve added some pen marks over the top to enhance the effect here and there. I don’t know if it’s because this paper hasn’t been sized, or whether the surface is just too soft. The reason doesn’t really matter; the fact is it doesn’t work as I’d expected. But now I know, having seen for myself.

As always, I can see some of these designs working in textiles with stitch, but for now it’s just an exercise on paper. It’s been a hectic week, and paint on paper is one of my best ways to relax and recover some equilibrium.
I use a separate small square sketchbook for testing paint colours before committing to the thing in progress, and I really like the little abstract compositions that happen purely by accident:

Another long bank holiday weekend here in the UK – whatever your plans are, enjoy some time out.
