i bought the fabric from the fabric store near my house.
altogether it was 16 dollars and if that's to much you can go to wal-mart and get 5 dollar flat sheet and do the same thing :p
i cut the green ones because i wanted it to fit the window just right, but with the gray ones i didn't cut them.
first get your fabric and then you can sew or glue it i cant sew that well so i hot glued mine;D you get the saw affect.
any questions just ask.
sorry for the crappy pictures
thanks for sharing nattie gurl
