You need to get camping grommets and small bungee cords at the supply store. lay down the fabric, place the insulation on top, then wrap the edges around and figure out where the grommets should go so the bungees will hold it with a little stretching. That should do it until you get frames or something better. Good Luck,

Nice idea, but I've used those grommet kits before, pain in the A$$, these are frameless traps I want to make, framed ones are easy to make, done 6 of those already.
