I hang them on the wall, put them on the easel or lay them on the table. Either I sit down or I stand up. I turn them around and upside down. I study them from up close and far behind.
Sometimes I get extremely tired of them and just want to throw them in the garbage and other times I look at them and it feels quite ok, even good! But I'm never 100% satisfied, ever.
