My Advent Calendar features a symbol on the first and last days and a letter on each of the other days. These letters and symbols are very easy to spot so there's no searching this year. The letters are all mixed up and on the 24th December they will need to be sorted to solve the message from me.
Many baubles have been collected over the years and this year I have noted that a silver theme for the tree might be the order of the day. Mind you, I've collected all sorts of coloured baubles from car boots and the CS so perhaps I should have a rainbow mix.
I'm linking my Advent Calendar with Julie's Scrapbook.
