Opps...I almost forgot! It started getting dark so I rushed out to take the pics I promised...here they are, sorry for the poor quality, I can take more in the daylight this weekend. These will have to do for now ~
Basically, each finished window awning is exactly the size of the window plus the valance (hanging down part) at the bottom. They each have two pockets at the bottom corners and two or three "female" snaps at the top (two on all the windows except the back one which is bigger). The window frames have corresponding "male snaps riveted onto the frames. I used stainless steel rivets & snaps for this because I felt they were stronger.
Of course if you have Corning frameless windows, these awnings won't work for you. I have two different style frames on our windows, the front & back are different from the sides. I don't use a front window awning because we have the fiberglass rock shield there.
To use them you slip the pockets on the bottom corners of the open window and snap the tops to hold them in place. You
can close the windows with them on, but not latch them. I am lucky all my windows are the same size, except the back one, so the awnings are all interchangeable. If your window sizes vary or if your snaps are a little "off" you may need to label which ones go where.
