That mesh note holder seems way to high for a pot holder.

If you want cheap and light, just take a small flat metal esbit holder (can be anything from a tin lid to just thick foil) and use tent stakes, thick bend metal wire to form a metal pot holder or use the metal mesh of a disposable BBQ (keep the foil tray too and cut it in to a windscreen) and make a circle.

Examples what type holder I have made in the past for my DIY alcohol stoves.
