You can download 'The Royal Wedding Official Programme' - free.
If you havn't seen it already you may like it. It has some excellent information, maps and photographs. It is a very useful guide to the 'pomp and ceremony'.
My plan for the day includes going to my parents to watch the 'ceremony' and I may crochet some 'commemorative' red, white and blue Granny Squares to make my 'Poor old Blanket' feel a bit regal and important. I am all for this wedding, it is afterall an extra days holiday. Three cheers for Royal Weddings!
