I don't know if I have a photo handy or not. We might make this weekend though if so I will take some step by steps.
It would be similar to what is listed here.
(note the show all steps button by the photo strip for easier reading)
We use smaller bottles that fit in the window sill and use a coffee filter instead of newspaper and plastic. We have also found the coffee filters to hold the dirt in fine for the most part so do not need to drill holes in the cap.
So our version has a few less steps! It has always worked well for us.
