Went on the link to the website but its still not made exactly clear what this tradition is....
I think its all aboout placing an elf doll on the shelf who observes the DCs behaviour then reports back to the Big Man, am I right?
I've seen so many references to this on MN and if its anything like the Elves' Hamper which I nicked last year and was truly gorgeous, then I want a piece of it!!
