New Curtain for My Son's Old House, With the Help of My Grand Daughter

My son bought a ruined house in the old historic centre of Porto. Being an architect he decided to rebuild it, and moved from London to our home town (when I first found the house and suggested him to buy it,  that was my purpose, to  make him comeback... )
The little house is now so cozy , and as i feel i have some responsability in the process, I decided to make something with my hands. Well, I love to make crochet, but usually it looks very feminin.  So I made this curtain, to the front window, so that he can see the narrow street, get all the sun light , have some privacy trying to give it a modern non-feminin look.
The pattern just emerged as the work was beiing done. I tried to represent the spiderwebs the house had, the irregular stone, even the woodworms nests...
My granddaughter help me putting the courtain in place.
