All
Thanks for the comments on my ideas....I am getting a feeling that there should be perhaps 2 pins... a 'smart' one, (I personally prefer the second one I did - the right hand one in the pic), and a variation of the fun cartoon Jumbo (which I like too!).
To save re-inventing the wheel (I'm supposed to be,er, revising for a Human Remains written!), if someone can get a much better quality rendition of the Jumbo to me via my email address, I'll render it into 'tiepin' form...
G'night
