thanks both,
I have indeed been wandering about ebay, Della, which is probably why I am so confused. I am finding prices from 4.99 through to 120, which seems rather a wide range for one designer. But it looks to me that the pure square Harlekiini are the ones making the money, and I wondered if it was just "ebay-itis" or a true summary of the desirability.
it doesn't help that ebay is just coming out of its summer slump, so lots of the pricing is uncharacteristic of the usual prices achieved.
