Sandra Walters has never watched an episode of Dr Who -- but she has memorised the trademark outfits of each of the famous timelords, down to their bowties and scarfs.
When not teaching technology at Featherston School, Sandra is usually knitting, her specialty being characters from science fiction and pop culture: from Mr Spock, to Lady Penelope to hordes of Ewoks and Daleks.
For the past year, she has supplied her cuddly heroes and villains, no more than 20cm tall, exclusively to Featherston gift shop Dandelion where they have been snapped up by sci-fi fans of all ages.
With mail orders for her characters coming in thick and fast, Sandra is often in front of the television, wool in hand, making pixie ears for Spock, sewing on Princess Leia's famous buns, or stitching lettering on a TARDIS.
But she's not likely to be watching any of the programmes her characters appear in, not being much of a sci-fi devotee.
