I built a dog door from scratch, but I'm stumped on what to use for the plastic flaps. My first thought was to use a car mat, but I really want it to be transparent, and all the transparent flaps I saw had the little plastic feet on the bottom (perhaps I could cut these off, but still a pain). I also looked at Walmart at shower mats, place mats for a dining table, etc., but the selection of transparent mats was pretty much non-existant.
Anyone have any good ideas or know where I can find some thick transparent plastic that would be good for a dog door?
Thanks, Dustin
