Where's the best place to buy soft cellular blankets?

[Moomin1000]

They all seem rough :-)

Buy the rough ones, wash them at home with fabric softener and they will be fine.

I've got some really nice John Lewis ones, definitely softer than the ones I got from Mothercare.

Babies R Us are by far the best I've seen - wash up lovely.

The Mothercare ones seem threadbare and hard :(
