Culture(d)

I probably shouldn't be cheating on my own challenge topics but I had this idea for a blip today which so nearly fitted but not quite.

These are my cultured pearls. Ian bought them for me. He went on a work trip to China quite soon after we met and brought these back for me. I didn't realise that each pearl is individually knotted onto the string so that if the string breaks they don't scatter all over the floor. The knots look quite noticeable here but not so much when they're being worn. I like the idea that these were made for me by some sea creature.

Igor's joke of the day "Cultured pearls? How many 'O' levels have they got?"........sorry.
