Window Curtains

I was playing around with window coverings, I cant leave the windows as is because there is nothing really behind them and they are all 3 sided. So I wanted to have a fabric texture without having to use fabric because that defeats the my whole challenge of using just paper, so I experimented with white tissue paper; I tried folding and creasing the tissue paper but it didn't turn out how I wanted it, so then I started to crinkle and twist the tissue to make it less stiff and I am happy with the result. The only thing now is that I have to figure out other types of window coverings, I don't want all the curtains to be the same.
