I don't want to take food out of anyone's mouth but I made a pair of
those screens with $12 worth of mosquito netting and about 1/2 hour on
a sewing machine. Get a piece of no-see-um screen at a camping store as
wide as your door and about a foot longer than 4 window heights. You
can get fancy on your bad self and cut the angle at the front of the
door or just do what I did which is essentially just make a "bag" out
of mosquito netting as wide as the door and about 3-4 inches taller =20
that the window (fold it over and sew up the two sides). You open
your door, roll down your window, toss the "bag" over the top of the
door and shut the door---dingity-dang, you've got yourself a double
layer of netting to keep the mozzies from taking a blood sample. You'll
have a little excess screen flapping around if you don't follow the
angle of the front of the door, but hey---its mostly dark when you're
camping so who'll notice?
