Mitch started this thread by wanting to make his own. Youtube has lots of guides, but I like this pillow trap and the video shows how it is done. I have not yet had time to make one. The metal mesh holds itself open better but I'm sure it would be more durable, lighter, to use the plastic hex mesh or coated metal. The metal hardware cloth with 1/4" squares would work too but might be quite stiff to work with and lots of sharp edges when cut.
