Fear of Flying.......insects

Today was the day--I had to varnish the Rt. 58 alkyd painting for the upcoming exhibit. In painting, I find two things nerve-wracking--signing my name and applying varnish. According to directions, varnish should be applied in a dust-free environment (ha). I placed a tarp on the floor of the porch and walked softly. It worked. I moved the painting into the workshop for the night. My fear now is that a tiny bug will fly into that blue sky and be trapped.

Tomorrow--isolation coats and varnish for the acrylic paintings. Do other painters sweat through this?

Don't recognize the bug above? It's a Buggs Island Wilkerdoptra!
