Down here in NZ (and in Australia and the UK as well), we call them cushions. In the US they are called pillows. Sometimes, however, we might decide to call them throw pillows! Very confusing.
First samples of this particular pillow/cushion species have just arrived, and very lovely they are too. I'd say they're just right for a kid's room because of their smooth, soft snuggly fabric, bright long-lasting prints and very important ability to be chucked in the washing machine! (the cover, that is - the insert would need to be hand washed).
Do have a peek at our new cushion collection - it's being built up over the next wee while to include many of my favourite prints and patterns. And just so you know, suggestions for new designs are gratefully received!
