Porch Curtains

We have a small screened in porch that has become my husband's sanctuary.  He loves sitting on the porch reading where he can hear the birds, feel the breeze, and......bake in the sun.  In the summer, the patio can be hot at times, so I would love to put up some porch curtains for the times of day that the sun becomes unbearable.  I'm still not sure how I can go about this, but here are some photos I found online for ideas.
