Looking back, I think this was a very nice diptych once upon a time...

But then I thought it could be improved! *groan*
I layered several glazes over the fuschia & brown colours, losing the lovely transparency of the fuschia & richness of the brown. I knew immediately that I was making a big mistake, but I kept adding more glazes, hoping to recapture what I'd lost.
Silly girl. One can never go back, only forward. Which is why knowing when to stop is a major part of the art-making process.

Finally, I stopped. I looked at the mess I'd made. Then quickly I thrust them out of sight behind some other half-finished work.
There they languished for many moons. Occasionally I would peek at them and tried to think what I could do to solve this mess. No ideas came.
Then last night I suddenly realized my time on 30day is two-thirds finished! Have I been keeping up? How many works have I made, how many still to go? The slow process of layering glazes on those 25 small canvasses seems like a crazy idea - I want to do something, quick!
Ok, haul out the old abandoned diptych & have another look. Don't think too much. Just go with my gut reaction. I want to obliterate these two, make them go away. Too much work to try to make anything beautiful of them now...
I know! Paint them black!
Undiluted black paint, just a little dryer: feeling impatient. Use a large brush. How satisfying.

Hey, not bad. At least now I can see the sewn design again, not distracted by lousy colours.
Difficult to photograph, can't get even light. Try to adjust in photoshop, but still not great. Oh well.
(Have you ever tried to photograph a totally black painting? It's very hard to do!)
This afternoon went back to look at them, still think they're not bad. The black paint is dry. Good.
Mix white paint with some solvent, very thin wash. Use the same big brush, slap it on quick. It's not evenly applied but I don't care.

The white paint pools into the ridges & textures of the surface - more interesting than a uniform coating. I like how the brush left its mark in the top parts, where there is not much sewing.
Are they finished?
Dare I risk making the same mistake twice by continuing to add more glazes, when the result now is "good enough"?
I am too much a perfectionist, I still think there is room for improvement here. But I am also afraid. I think I will call them finished & think of them as such.
Unless, of course, sudden inspiration hits...
