Catherine, I hope the tongue-in-cheek nature of my post was recognised...
I must confess that I've never encountered a shower stall that wasn't big enough to dry myself with a flannel; if it's big enough to get myself wet and wash everywhere, I figure that it's big enough to dry myself everywhere. Maybe that comes from 30 years practice of drying with a flannel in the shower; starting with the dirty student trick of saving the towel washing and continuing, well, because it works, I guess...
Admittedly, I'm a fairly slightly-built bloke. I'm sure Arnie might have trouble in some of the cubicles I've seen...
Captain Paranoia - I got it but I like the space because I'm not the most agile of people - one too many times of standing on a wet floor in my socks and I hate putting boots on with no socks.
ok take a new blue J cloth, just incase the colour matters, weight 11 grams +/- 1 gram.
take a new asda super aborbent yellow cloth weight 18 grams. Cut the yellow down to 11 +/- 1 grams. Lay both in a flat tray of water. Lift out and drain for 10 seconds in the same way. Weight of J cloth 76 grams. weight of super absorbent yellow cloth 134 grams. I would say that difference is beyond experimental error.
only proves one holds more water than another. nothing to do with absorbency or how long they remain wet. you need a merino cloth. attached to a sheep for portability.
One of my bits of 'spare' kit tends to be a pair of pertex-like windproof trousers. I rarely wear them on the go, so they stay clean enough to serve as a towel. They dry so fast that I have managed to use them to dry myself off and then put them straight on, albeit damp.
