Last night, about an hour or so after I'd finished painting about 1/4 of the tent yellow, it started raining. I didn't worry too much because previously leaving the yellow paint out in the rain didn't seem to do much to it. Obviously, I didn't take into account what still-damp paint would do.( the entire tent panel )
Just to clarify -- because we live on a very open,windy hillslope, we get a lot of things blown in, and one can assume blown away.
To cut down on the amount of stuff in the backyard that could go missing, I had folded the canvas in half, so the top side could be painted and the other half could act as a drop cloth.
With the rain, it meant that the paint soaked through both layers of canvas, and then pooled underneath on the concrete.
So there is a dry, unaffected half, a splotchy yellow half, and a pale yellow half. ( The three shades of yellow )
The other fantastic thing that has happened, is now all the dirt that blows in has stuck to it, so it's now a filthy, blotchy piece of painted canvas. But if anyone asks, it was intentional.(It doesn't look at all bad in the photos but in person it looks rather grotty.) Yet the half that had been dried and finished didn't run at all, it was just a bit damp when I unfolded it all to dry in the sun this morning.( Last photo -- the cool pattern I'm painting on. )
