those humidifier things you hang on the radiator?

[brimfull]

where can I buy them,crinkling up like a prune!

Betterware in attractive rose-print ceramic
here in handmade arty swirls.

I'd just put a dish of water on the windowsill myself...

slightly better Rennie Mackintosh one

have just passed a page that suggests hanging wet towels over radiator for the same effect (and obviously has the bonus of drying your laundry too).

thanks wet towels then
