I like the patterns on these huge shells that sit on the bathroom window-sill.

Re yesterday's Christmas wreath competition:
Your votes have been counted and verified, and the winner is.......................(long nail-biting pause)...................................the middle one! Thank you for taking part. Please do not vote now, because phone-lines have voting has closed and you may still be charged your vote will not count. The Santa wreath is already in place.

(Sorry, maybe I'm watching too many phone-in competitions on television.)
