There was another similar thread like this and wax paper was suggested. After reading, I have tried this material and really like the results compared to the screen that I have used in the past. Before putting the paper over the pan I have been crumpling it up and then GENTLY unballing it (took a couple times to get the feel for it). I personally like how the wax paper forms around the pan, and dirt can somewhat be packed inside the jaws with out going under the pan. The screen will not conform to the pan and allow dirt to be packed inside the jaws, at least not above the screen. This year I have had one set that was "dug at", not dug up, that had a screen. I replaced the screen with wax paper and 2 days later had a coyote, maybe a coincidence, I don't know. I think I will try Hal' s method of using coffee filters and see what happens. Thanks for some good advice here.
