Re: How do you - make holes (in foil)?
I use an oversized safety-pin to poke the holes.
As to pattern:
- for standard clay bowls, start on outside edge and circle into the center, semi-skattered.
- smiley bowls, 3 rings: outside, tight inside, even spaced middle area.
- phunnels: dependant on shisha using. Tangiers - as many as the foil can hold without ripping. Everything else (Lay, AF, Smiley) 2 rings. 1 along outside edge and 1 tight against mod.
