The custom is to unroll the m'gila and fold it over, 'page' over 'page', before reading it in public on Purim, then to roll it up again before reciting the b'racha after the reading. Suppose there's no one at hand to help you hold it in place on a lectern or table while you read it. You will want to fold it in such a way that
- the 'page breaks' are between columns of text,
- the m'gila will not roll up
- even while you're 'turning the page',
- it's easy to 'turn the page', and,
- preferably, it's fast and easy to roll it up as soon as you've finished reading.
I haven't found such a folding method, and I struggle with my m'gila every time I read it.
Can you recommend a folding method, preferably (though not necessarily) one that
- has worked in practice, and
- works even if the m'gila is being held (there's no lectern or table)?
Bear in mind that (at least in my m'gila) not all columns are the same width, so not all 'pages' will be the same width if the 'page breaks' are between columns.
