If extra bedding laundry is a problem atm, you may find a duvet
protector useful, as supplied to the hotel trade. I'll look out the
number if you want.

These are *Hungarian* goose down, so you take them down to the river, to
that nice flat stone...

But Mary hasn't got a tumble dryer, or access to Hungarian summer sunshine.

I always washed the kids' synthetic duvets in the bath, by trampling
up and down on them.

I usually do my double down duvet in the washing machine, working on the
principal that it will compress when wet. But having terminally damaged
the bearings of the last washing machine, I thought I perhaps better try
hand washing, which of course left it too wet to tumble dry, so I dried
it by draping it over the garden bench in the sun, and turning it
frequently. It worked OK. I suspect the demand to tumble dry is to
overcome the problem of having it take several days to dry through, and
rotting in the process.
