This window screen (was used to protect flowers from the sun) I made yesterday for my thirties house. It was made out of a scoubidou string which is strengthened by iron wire. After it was made in the right form it was painted with two coats of gesso. After that I painted it with dark woodstain. And finally I glued some fine fabric (net) onto the frame.
Of course I had to make a flower to be protected by the screen ;-)
