Re: Tight Foil on bowl
1 layer of HD foil, tighten and you would normally around the edge and bowl body itself. When you poke the holes, you want to hold the foil tight with your free hand so you dont push down on the foil. That should keep your foil in place fine. Its more the poking of the holes that gives you a sag in the foil than the coals weight since you will be resting part of the coal on the edge of the bowl.
