To the best of my recollection this is my old Scout blanket. I and my brother and sister each had one, each being decorated a different way depending on what we'd aggregated through Cubs, Scouts, Girl Guides (I should clarify that only one of us was in that) and possibly some parts beyond - although I suspect that by the time we were Venturers or Rovers the badge thing wasn't so prominent. There are plenty of examples of this kind of thing on the internet, and it was a NZ phenomenon, too, as a particularly fine example belonging to friends (but on an army blanket rather than the grey here) indicated a few years back.
my one and only Jamboree. That said, I don't see any badge of my actual jamboree there... hmmm.
The rest of the blanket interests me more these days, and actually has more personal relevance, because it tells a story somewhat of the family holidays we went on up to about the time I was ten. The wedge-shaped felt tourism pennants, the subject of ongoing back car seat debates about whose turn it was to get the next one; does anyone make pennants for towns and cities anywhere? I'm going to find out!
