Here is what I am doing for a pot holder - I was actually working on it tonight. Buy a MSR stove windscreen. Cut it in half at the center point. Fold it into thirds, and then make a ring that fits around your popcan stove. Leave about one inch of space between the can and the foil, and fold the foil so the pot rests about 1/2 inch above the top of the popcan. In the sides of the foil, drill 2 offset rows of holes 1/4 inch diameter every inch…this allows for increased air flow.
The foil ring will support well of 20 pounds of weight. Since these directions are confusing you may want to e-mail me if you are interested.
