I would question who told you that hooks cannot be screwed into your window frames. I am looking at ours held up by tension wire and screwd in hooks! I used a 1 or 2mm drill to make a small hole and then screwed them in.
Obviouly you can't drill near the edge of the frame where the glass is recessed in but there is plenty of room above the "glass" line up in the corners! More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
